From 5cfe911880a336238518bee50d1ce5b65fffc5c7 Mon Sep 17 00:00:00 2001 From: airborne12 Date: Sat, 27 Jun 2026 01:24:40 +0800 Subject: [PATCH 01/86] [feature](be) Add SNII inverted index storage format ### What problem does this PR solve? Issue Number: None Related PR: None Problem Summary: Doris only routed inverted index files through the existing V1/V2 storage implementations. This change adds SNII as an independent inverted index storage format, copies the SNII core reader/writer/query implementation into BE, and branches the Doris index file reader/writer paths so SNII reads, writes, queries, and null bitmap handling go through SNII code. SNII reuses Doris analyzer integration only; it does not route SNII storage through the existing CLucene directory/compound reader paths. SNII currently supports string and array string inverted indexes, while numeric/BKD indexes are rejected for this format until BKD support is implemented. ### Release note Add SNII as an inverted index storage format for string inverted indexes. BKD indexes are not supported with SNII yet. ### Check List (For Author) - Test: Build - `./build.sh --be` - `./build.sh --fe` - `build-support/clang-format.sh` - `build-support/check-format.sh` - `build-support/run-clang-tidy.sh --build-dir be/build_Release` attempted; it failed because clang-tidy could not resolve `stddef.h` in this toolchain and also reported pre-existing unrelated diagnostics. - Behavior changed: Yes. Tables using `inverted_index_storage_format=SNII` route string inverted index storage/query/null handling through SNII and reject BKD indexes. - Does this need documentation: Yes.

Issue Number: None Related PR: None Problem Summary: This change completes the SNII inverted index storage-format split by routing SNII reads and writes through the SNII implementation, preserving Doris IO context during SNII file reads, bounding expanding queries before materializing all prefix terms, and rejecting unsupported SNII operations such as BKD-backed indexes, ANN indexes, and BUILD INDEX. It also avoids applying old CLucene index-compaction/drop-index paths to SNII files and adds focused FE and regression coverage for unsupported paths. ### Release note SNII inverted index storage format rejects unsupported BKD, ANN, and BUILD INDEX operations. ### Check List (For Author) - Test: - Build: ./build.sh --be --fe -j 192 - Build: ./build.sh --be -j 192 - Unit Test: ./run-fe-ut.sh --run org.apache.doris.nereids.trees.plans.commands.IndexDefinitionTest,org.apache.doris.alter.IndexChangeJobTest - Regression test: ./bootstrap.sh run -- --run -d inverted_index_p0/storage_format -s test_storage_format_snii -forceGenOut; ./bootstrap.sh run -- --run -d inverted_index_p0/storage_format -s test_storage_format_snii - Format: ./build-support/clang-format.sh; ./build-support/check-format.sh; git diff --check - Static Analysis: ./build-support/run-clang-tidy.sh and ./build-support/run-clang-tidy.sh --build-dir be/build_Release attempted; failed because clang-tidy could not resolve system stddef.h and also reported existing large-function/NOLINT diagnostics outside the safe scope of this SNII integration. - Behavior changed: Yes. SNII explicitly rejects unsupported BKD/ANN/BUILD INDEX paths instead of falling through to non-SNII index handling. - Does this need documentation: No --- be/src/snii/format/null_bitmap.h | 3 + be/src/snii/query/internal/term_expansion.h | 3 +- be/src/snii/query/phrase_query.h | 8 +- be/src/snii/query/prefix_query.h | 7 +- be/src/snii/query/regexp_query.h | 7 +- be/src/snii/query/wildcard_query.h | 7 +- be/src/snii/reader/logical_index_reader.h | 10 +- be/src/storage/compaction/compaction.cpp | 6 + be/src/storage/index/index_file_reader.cpp | 10 +- be/src/storage/index/index_file_writer.cpp | 12 +- be/src/storage/index/index_file_writer.h | 8 +- .../snii/core/src/format/null_bitmap.cpp | 12 +- .../snii/core/src/query/phrase_query.cpp | 49 ++++--- .../snii/core/src/query/prefix_query.cpp | 22 ++-- .../snii/core/src/query/regexp_query.cpp | 29 +++-- .../snii/core/src/query/term_expansion.cpp | 25 ++-- .../snii/core/src/query/wildcard_query.cpp | 26 ++-- .../core/src/reader/logical_index_reader.cpp | 99 ++++++++++---- .../storage/index/snii/snii_doris_adapter.cpp | 108 ++++++++++++++- .../storage/index/snii/snii_doris_adapter.h | 22 +++- .../storage/index/snii/snii_index_reader.cpp | 82 ++++++++---- .../storage/index/snii/snii_index_writer.cpp | 11 +- be/src/storage/index/snii/snii_index_writer.h | 2 + be/src/storage/task/index_builder.cpp | 7 + .../plans/commands/info/BuildIndexOp.java | 5 + .../plans/commands/info/CreateTableInfo.java | 6 +- .../plans/commands/info/IndexDefinition.java | 15 ++- .../doris/alter/IndexChangeJobTest.java | 42 ++++++ .../plans/commands/IndexDefinitionTest.java | 64 +++++++++ .../test_storage_format_snii.out | 3 + .../test_storage_format_snii.groovy | 123 ++++++++++++++++++ 31 files changed, 698 insertions(+), 135 deletions(-) diff --git a/be/src/snii/format/null_bitmap.h b/be/src/snii/format/null_bitmap.h index efe5880a101f55..21c6f92be59709 100644 --- a/be/src/snii/format/null_bitmap.h +++ b/be/src/snii/format/null_bitmap.h @@ -76,6 +76,9 @@ class NullBitmapReader { // Number of distinct null docids in the bitmap. uint32_t null_count() const; + // Copies the decoded bitmap into the caller-owned Roaring object. + void copy_to(roaring::Roaring* out) const; + // Total doc count of the logical index, as recorded by the writer. uint32_t doc_count() const { return doc_count_; } diff --git a/be/src/snii/query/internal/term_expansion.h b/be/src/snii/query/internal/term_expansion.h index 3b9753b4df267e..3393c31dc8457a 100644 --- a/be/src/snii/query/internal/term_expansion.h +++ b/be/src/snii/query/internal/term_expansion.h @@ -1,5 +1,6 @@ #pragma once +#include #include #include @@ -16,6 +17,6 @@ using TermMatcher = std::function; // DictEntry and block bases, so callers avoid a second lookup per expanded term.

Before this change, SNII opened remote index files without the same file-cache options as V3 and only part of the IO context reached SNII/CLucene readers, so query profiles could not compare logical requested index bytes, physical index reads, and serial read rounds. This change routes SNII index file opens through Doris file-cache options, propagates copied inverted-index IO context through SNII reads, records request/read bytes and read round counters for both SNII and CLucene index readers, and exposes those counters in the file-cache profile reporter. SNII and V3 inverted index scans now expose additional IO profile counters for request bytes, physical read bytes, range read count, and serial read rounds. - Test: - Unit Test: ./run-be-ut.sh --clean --run --filter='DorisSniiFileReaderTest.*:DorisFSDirectoryTest.FSIndexInputReadInternalRecordsIndexIOStatsAndContext:FileCacheProfileReporterTest.*' -j "192" - Unit Test: ./run-be-ut.sh --run --filter='DorisSniiFileReaderTest.*:DorisFSDirectoryTest.FSIndexInputReadInternalRecordsIndexIOStatsAndContext:FileCacheProfileReporterTest.*' -j "192" - Format: build-support/clang-format.sh; build-support/check-format.sh; git diff --check - Static Analysis: build-support/run-clang-tidy.sh --build-dir be/ut_build_ASAN attempted; failed because clang-tidy could not resolve system stddef.h and also reported existing large-function/C-header/NOLINT diagnostics outside this change. Clear new SNII adapter style warnings were fixed. - Behavior changed: Yes. SNII remote index file reads now use the same Doris file-cache reader options as V3 when file cache is enabled, and both SNII/V3 report additional profile counters. - Does this need documentation: No --- be/src/exec/scan/olap_scanner.cpp | 5 +- be/src/io/cache/block_file_cache_profile.cpp | 17 ++ be/src/io/cache/block_file_cache_profile.h | 5 +- be/src/io/io_common.h | 4 + be/src/storage/index/index_file_reader.cpp | 4 + .../inverted/inverted_index_fs_directory.cpp | 15 +- .../storage/index/snii/snii_doris_adapter.cpp | 57 +++++- .../storage/index/snii/snii_doris_adapter.h | 15 +- ...block_file_cache_profile_reporter_test.cpp | 16 ++ .../storage/index/snii_doris_adapter_test.cpp | 168 ++++++++++++++++++ .../inverted_index_fs_directory_test.cpp | 54 +++++- 11 files changed, 339 insertions(+), 21 deletions(-) create mode 100644 be/test/storage/index/snii_doris_adapter_test.cpp diff --git a/be/src/exec/scan/olap_scanner.cpp b/be/src/exec/scan/olap_scanner.cpp index a9ef277c373002..cb42420e1ab687 100644 --- a/be/src/exec/scan/olap_scanner.cpp +++ b/be/src/exec/scan/olap_scanner.cpp @@ -153,7 +153,10 @@ static bool has_file_cache_statistics(const io::FileCacheStatistics& stats) { stats.inverted_index_bytes_read_from_remote != 0 || stats.inverted_index_bytes_read_from_peer != 0 || stats.inverted_index_local_io_timer != 0 || stats.inverted_index_remote_io_timer != 0 || - stats.inverted_index_peer_io_timer != 0 || stats.inverted_index_io_timer != 0;

Issue Number: None Related PR: None Problem Summary: SNII phrase and phrase-prefix queries spent most CPU time re-scanning phrase candidate docids for every PRX chunk and allocating per-doc expected tail position vectors. On the 10B TextBench cloud benchmark, MATCH_PHRASE 'failed order' took 253.0s wall / 3942.9 CPU-s and MATCH_PHRASE_PREFIX 'failed ord' took 438.3s wall / 6939.5 CPU-s before this optimization. The fix starts PRX candidate filtering from the chunk's first docid, keeps an all-selected fast path, stores expected tail positions in flat CSR-style arrays, and uses a single exact-term fast path for phrase-prefix expected tail positions. The same benchmark now runs in about 3.8s / 59.3 CPU-s for phrase and 3.9s / 61-62 CPU-s for phrase-prefix. ### Release note None ### Check List (For Author) - Test: - Unit Test: ./run-be-ut.sh --run --filter=SniiPhraseQueryTest.* - Manual test: release BE build and cloud_sim E2E TextBench phrase benchmark - Static check: git diff --check;

Issue Number: N/A Related PR: N/A Problem Summary: SNII MATCH_PHRASE in cloud mode spent most CPU in selective PRX/PFOR decode, candidate ordinal materialization, and generic two-term position checks. This change removes per-doc ordinal Status overhead, uses selected PRX ranges to compact dense PFOR decodes, decodes sparse PFOR runs through a stack buffer, and adds a two-term phrase merge path. In cloud_sim PH5 on textbench_10b_perf.otel10b_phrase40_snii, BE CPU is now about 47.67s on average with SQL and inverted-index query cache disabled, down from roughly 55-59s observed before these optimizations. ### Release note None ### Check List (For Author) - Test: Unit Test and Manual test - Unit Test: ./run-be-ut.sh --run --filter=SniiPhraseQueryTest.*:SniiPrxPodTest.* - Build: ./build.sh --be -j 192 - Manual test: deployed BE to cloud_sim and ran PH5 benchmark under /mnt/disk15/jiangkai/textbench/runs/20260628_phrase_cpu_opt_final_refactor_nocache - Static check: git diff --check;

Issue Number: N/A Related PR: #64909 Problem Summary: SNII phrase and phrase-prefix queries spent most CPU in docid intersection, selective PRX/PFOR decode, and position verification. This change avoids generating PRX ordinals for full on-disk windows so the reader can use the full CSR path, folds selective PRX count validation into selected-range construction, removes hot-loop overflow helper calls from two-term phrase matching, and routes single-tail phrase-prefix queries through the streaming phrase path to avoid materializing all expected tail positions. On the 10B cloud_sim PP5 cold query, SNII BE CPU improved from 72.20s to 63.29s and HWM dropped from 20.26GB to 7.08GB. ### Release note None ### Check List (For Author) - Test: Unit Test and Manual test - Unit Test: ./run-be-ut.sh --run --filter=SniiPhraseQueryTest.*:SniiPrxPodTest.* - Static check: build-support/check-format.sh;

Issue Number: N/A Related PR: N/A Problem Summary: SNII high-df term and phrase queries spent avoidable CPU in vector-to-Roaring materialization, dense docid expansion, selected PRX range construction, repeated final-candidate filtering, and sorted docid conjunction. The CPU profile showed phrase execution dominated by docid conjunction, PFOR PRX decode, and selective PRX CSR compaction instead of remote I/O. This change streams eligible term, prefix, regexp, and wildcard query results directly into Roaring, emits dense docid windows as ranges, carries PRX doc ordinal context through phrase execution, builds selected PRX count ranges during PFOR decode, skips redundant final-candidate filtering, and adds sparse galloping paths for docid conjunction. It also caps conjunction reserve sizes to the maximum possible match count and refactors the SNII reader query dispatch to keep the storage reader control flow smaller. ### Release note None ### Check List (For Author) - Test: Unit Test / Manual test - Unit Test: ./run-be-ut.sh --run --filter=SniiPhraseQueryTest.*:SniiTermQueryTest.*:SniiPrxPodTest.* - Manual test: ./build.sh --be -j 192 - Manual test: deployed BE to cloud_sim and ran support_phrase MATCH_PHRASE smoke query - Manual test: cloud_sim cold benchmark for OP_term_high_df, PH5_phrase_failed_order, and PP5_phrase_prefix_failed - Static check: git diff --check; build-support/check-format.sh - Static check: clang-tidy was attempted with build-support/run-clang-tidy.sh --build-dir be/build_Release, but this environment failed before useful changed-line validation with missing stddef.h/toolchain include errors and pre-existing full-file warnings. - Behavior changed: No - Does this need documentation: No --- be/src/snii/query/docid_sink.h | 20 ++ .../snii/query/internal/docid_conjunction.h | 2 + .../query/internal/docid_posting_reader.h | 5 + be/src/snii/query/term_query.h | 3 + .../index/snii/core/src/format/prx_pod.cpp | 52 +++--- .../snii/core/src/query/docid_conjunction.cpp | 70 ++++++- .../core/src/query/docid_posting_reader.cpp | 92 +++++++++- .../snii/core/src/query/phrase_query.cpp | 89 +++++++-- .../index/snii/core/src/query/term_query.cpp | 8 +- .../storage/index/snii/snii_index_reader.cpp | 171 ++++++++++++------ be/src/storage/index/snii/snii_index_reader.h | 2 - be/test/storage/index/snii_query_test.cpp | 37 ++++ 12 files changed, 445 insertions(+), 106 deletions(-) diff --git a/be/src/snii/query/docid_sink.h b/be/src/snii/query/docid_sink.h index de08d24b9ce164..9fc5dc2d9739d3 100644 --- a/be/src/snii/query/docid_sink.h +++ b/be/src/snii/query/docid_sink.h @@ -1,6 +1,7 @@ #pragma once #include +#include #include #include @@ -14,6 +15,7 @@ class DocIdSink { public: virtual ~DocIdSink() = default; virtual Status append_sorted(std::span docids) = 0; + virtual Status append_range(uint32_t first, uint64_t last_exclusive) = 0; }; class VectorDocIdSink final : public DocIdSink { @@ -25,6 +27,24 @@ class VectorDocIdSink final : public DocIdSink { return Status::OK(); } + Status append_range(uint32_t first, uint64_t last_exclusive) override { + if (last_exclusive <= first) { + return Status::OK(); + } + if (last_exclusive > static_cast(std::numeric_limits::max()) + 1) { + return Status::InvalidArgument("docid_sink: range exceeds uint32 docid space"); + } + const uint64_t count = last_exclusive - first; + if (count > static_cast(docids_.max_size() - docids_.size())) { + return Status::InvalidArgument("docid_sink: range too large"); + } + docids_.reserve(docids_.size() + static_cast(count)); + for (uint64_t docid = first; docid < last_exclusive; ++docid) { + docids_.push_back(static_cast(docid)); + } + return Status::OK(); + } + private: std::vector& docids_; }; diff --git a/be/src/snii/query/internal/docid_conjunction.h b/be/src/snii/query/internal/docid_conjunction.h index f97ac781a2c364..3cb6cc42f5a294 100644 --- a/be/src/snii/query/internal/docid_conjunction.h +++ b/be/src/snii/query/internal/docid_conjunction.h @@ -36,12 +36,14 @@ struct TermPlan { struct DocidChunk { std::vector docids; std::vector prx_doc_ordinals; + uint32_t prx_doc_count = 0; bool windowed = false; uint32_t window = 0; }; struct DocidSource { std::vector chunks; + bool docids_are_final_candidates = false; }; Status resolve_query_term(const snii::reader::LogicalIndexReader& idx, const std::string& term, diff --git a/be/src/snii/query/internal/docid_posting_reader.h b/be/src/snii/query/internal/docid_posting_reader.h index cf297d4082ccd9..bf5927b5857335 100644 --- a/be/src/snii/query/internal/docid_posting_reader.h +++ b/be/src/snii/query/internal/docid_posting_reader.h @@ -5,6 +5,7 @@ #include "snii/common/status.h" #include "snii/format/dict_entry.h" +#include "snii/query/docid_sink.h" #include "snii/reader/logical_index_reader.h" namespace snii::query::internal { @@ -22,6 +23,10 @@ Status read_docid_posting(const snii::reader::LogicalIndexReader& idx, const snii::format::DictEntry& entry, uint64_t frq_base, uint64_t prx_base, std::vector* docids); +Status read_docid_posting(const snii::reader::LogicalIndexReader& idx, + const snii::format::DictEntry& entry, uint64_t frq_base, + uint64_t prx_base, snii::query::DocIdSink* sink); + // Batch counterpart for multi-term docid-only operators.

Issue Number: N/A Related PR: N/A Problem Summary: SNII phrase queries on the 10B cloud benchmark spent most CPU in PRX position decode, posting cursor iteration, and docid conjunction. This change adds a two-term phrase streaming path, uses an adjacent-pair prefilter for multi-term phrase verification, reuses candidate ranges during docid conjunction, and adds low bit-width PFOR unpack paths for common PRX count and delta widths. A near-dense ordinal shortcut was tested and removed because it regressed the PH5 and PP5 phrase cases. In the cloud_sim 10B cold benchmark, PH5 improved from 6181 ms wall time and 60.22 s BE CPU to 5794 ms wall time and 55.43 s BE CPU; PP5 improved from 6211 ms wall time and 59.82 s BE CPU to 6038 ms wall time and 56.26 s BE CPU. PH5 pprof shows pfor_decode self CPU reduced to about 11.4% after the low bit-width fast paths. ### Release note None ### Check List (For Author) - Test: - Unit Test: ./run-be-ut.sh --run --filter='SniiPforTest.*:SniiPhraseQueryTest.*:SniiTermQueryTest.*:SniiPrxPodTest.*' - Manual test: ./build.sh --be -j 192 - Manual test: cloud_sim PH5/PP5 cold benchmark at /mnt/disk15/jiangkai/textbench/runs/20260628_phrase_cpu_final_pfor_next_cold - Manual test: cloud_sim PH5 pprof at /mnt/disk15/jiangkai/textbench/runs/20260628_phrase_final_pfor_next_pprof - Static Check: build-support/clang-format.sh, build-support/check-format.sh, and build-support/run-clang-tidy.sh --build-dir be/build_Release - Behavior changed: No - Does this need documentation: No --- .../index/snii/core/src/encoding/pfor.cpp | 61 ++++++ .../snii/core/src/query/docid_conjunction.cpp | 83 ++++--- .../snii/core/src/query/phrase_query.cpp | 204 +++++++++++++++--- be/test/storage/index/snii_query_test.cpp | 78 ++++++- 4 files changed, 361 insertions(+), 65 deletions(-) diff --git a/be/src/storage/index/snii/core/src/encoding/pfor.cpp b/be/src/storage/index/snii/core/src/encoding/pfor.cpp index 19f6442185a556..98862d7f5ee8a9 100644 --- a/be/src/storage/index/snii/core/src/encoding/pfor.cpp +++ b/be/src/storage/index/snii/core/src/encoding/pfor.cpp @@ -89,6 +89,67 @@ Status bitunpack(ByteSource* src, size_t n, uint8_t w, uint32_t* out) { Slice buf;

Issue Number: N/A Related PR: N/A Problem Summary: SNII phrase queries on the 10B cloud benchmark still spent the largest CPU share in docid/ordinal intersection before PRX verification. The hot path had to intersect dense or near-dense candidate windows with term docids and produce PRX doc ordinals. This change adds a candidate-span fast path that directly accepts all term docids when candidates continuously cover the term span, adds dense/near-dense ordinal mapping for term spans with few missing docs, and fixes mixed dense/non-dense window output ordering by batching window work and flushing in original order. In cloud_sim PH5/PP5 cold benchmark, PH5 improved from 5794 ms wall and 55.43 s BE CPU to 5702 ms wall and 53.55 s BE CPU; PP5 kept similar wall time and reduced BE CPU from 56.26 s to 55.21 s. The inverted index read bytes, remote bytes, cache bytes, serial rounds, and IO counts stayed unchanged, so the improvement is from CPU-side algorithm work rather than reduced remote reads. A bulk dense append variant was tested and reverted because it regressed PH5/PP5. ### Release note None ### Check List (For Author) - Test: - Unit Test: ./run-be-ut.sh --run --filter='SniiPforTest.*:SniiPhraseQueryTest.*:SniiTermQueryTest.*:SniiPrxPodTest.*' - Manual test: ./build.sh --be -j 192 - Manual test: cloud_sim PH5/PP5 cold benchmark at /mnt/disk15/jiangkai/textbench/runs/20260628_phrase_final_cover_span_refactor_cold - Manual test: cloud_sim PH5 pprof at /mnt/disk15/jiangkai/textbench/runs/20260628_phrase_final_cover_span_refactor_pprof - Static Check: build-support/clang-format.sh, build-support/check-format.sh, git diff --check - Static Check: build-support/run-clang-tidy.sh --build-dir be/build_Release failed because the local ldb clang-tidy toolchain could not find stddef.h while parsing system headers - Behavior changed: No - Does this need documentation: No --- .../snii/core/src/query/docid_conjunction.cpp | 318 +++++++++++++----- be/test/storage/index/snii_query_test.cpp | 41 ++- 2 files changed, 272 insertions(+), 87 deletions(-) diff --git a/be/src/storage/index/snii/core/src/query/docid_conjunction.cpp b/be/src/storage/index/snii/core/src/query/docid_conjunction.cpp index a8f946e9c4f7bf..1ebb6c86a7471a 100644 --- a/be/src/storage/index/snii/core/src/query/docid_conjunction.cpp +++ b/be/src/storage/index/snii/core/src/query/docid_conjunction.cpp @@ -147,6 +147,44 @@ void append_candidate_range(CandidateIt begin, CandidateIt end, std::vectorinsert(out->end(), begin, end);

Issue Number: None Related PR: None Problem Summary: SNII phrase verification still spent CPU in per-candidate cursor/status handling for exact two-term phrases. Profiles showed PostingCursor::next and positions handling in the hot path while IO metrics stayed unchanged. This change reuses a shared PRX chunk decoder and adds a two-term chunk merge path for non-repeated phrases so overlapping chunks decode once and docids are verified with a linear merge. Repeated-term phrases still use the existing streaming path, and multi-term streaming is split into smaller helpers. On 10B textbench cold cloud_sim runs, PH5 CPU dropped from 53.55s to 48.07s and PP5 CPU dropped from 55.21s to 49.95s with identical IO bytes. ### Release note None ### Check List (For Author) - Test: - Unit Test: ./run-be-ut.sh --run --filter='SniiPhraseQueryTest.*:SniiTermQueryTest.*:SniiPrxPodTest.*:SniiPforTest.*' - Manual test: ./build.sh --be -j 192 - Manual test: cloud_sim BE redeploy and smoke MATCH_PHRASE / MATCH_PHRASE_PREFIX - Benchmark: textbench 10B cold PH5/PP5 comparison - Static check: build-support/clang-format.sh, build-support/check-format.sh, git diff --check; build-support/run-clang-tidy.sh --build-dir be/build_Release attempted but blocked by local clang-tidy system header resolution where stddef.h is not found. - Behavior changed: No - Does this need documentation: No --- .../snii/core/src/query/phrase_query.cpp | 419 ++++++++++++------ 1 file changed, 295 insertions(+), 124 deletions(-) diff --git a/be/src/storage/index/snii/core/src/query/phrase_query.cpp b/be/src/storage/index/snii/core/src/query/phrase_query.cpp index e5377e1071d527..72db2d628513e0 100644 --- a/be/src/storage/index/snii/core/src/query/phrase_query.cpp +++ b/be/src/storage/index/snii/core/src/query/phrase_query.cpp @@ -376,6 +376,85 @@ Status BuildPositionSourcesForCandidates( return Status::OK(); } +class PosChunkDecoder { +public: + void reset() { + chunk_ = nullptr; + offsets_by_prx_ordinal_ = false; + } + + Status decode(const PosChunk& chunk) { + chunk_ = &chunk; + ByteSource ps(chunk.prx); + offsets_by_prx_ordinal_ = false; + if (chunk.prx_doc_ordinals.empty()) { + SNII_RETURN_IF_ERROR(snii::format::read_prx_window_csr(&ps, &pflat_, &poff_)); + } else if (should_decode_full_prx_window(chunk)) { + SNII_RETURN_IF_ERROR(snii::format::read_prx_window_csr(&ps, &pflat_, &poff_)); + offsets_by_prx_ordinal_ = true; + } else { + SNII_RETURN_IF_ERROR(snii::format::read_prx_window_csr_selective( + &ps, chunk.prx_doc_ordinals, &pflat_, &poff_)); + } + if (offsets_by_prx_ordinal_) { + if (poff_.size() != static_cast(chunk.prx_doc_count) + 1) { + return Status::Corruption("phrase_query: full prx doc-count mismatch"); + } + } else if (poff_.size() != chunk.docids.size() + 1) { + return Status::Corruption("phrase_query: selected prx/doc-count mismatch"); + } + if (poff_.back() > pflat_.size()) { + return Status::Corruption("phrase_query: prx final offset out of range"); + } + return Status::OK(); + } + + Status positions(size_t doc_index, std::pair* out) const { + if (chunk_ == nullptr || doc_index >= chunk_->docids.size()) { + return Status::Corruption("phrase_query: decoded chunk doc index out of range"); + } + const size_t pos_index = + offsets_by_prx_ordinal_ ? chunk_->prx_doc_ordinals[doc_index] : doc_index; + if (pos_index + 1 >= poff_.size()) { + return Status::Corruption("phrase_query: prx ordinal offset out of range"); + } + const uint32_t begin = poff_[pos_index]; + const uint32_t end = poff_[pos_index + 1]; + if (begin == end) { + *out = {nullptr, nullptr}; + return Status::OK(); + } + if (end > pflat_.size()) { + return Status::Corruption("phrase_query: prx offset out of range"); + } + *out = {pflat_.data() + begin, pflat_.data() + end}; + return Status::OK(); + } + + inline __attribute__((always_inline)) std::pair + positions_unchecked(size_t doc_index) const { + const size_t pos_index = + offsets_by_prx_ordinal_ ? chunk_->prx_doc_ordinals[doc_index] : doc_index; + const uint32_t begin = poff_[pos_index]; + const uint32_t end = poff_[pos_index + 1]; + if (begin == end) { + return {nullptr, nullptr}; + } + return {pflat_.data() + begin, pflat_.data() + end}; + } + +private: + static bool should_decode_full_prx_window(const PosChunk& chunk) { + return chunk.prx_doc_count != 0 && + static_cast(chunk.prx_doc_ordinals.size()) * 2 >= chunk.prx_doc_count; + } + + const PosChunk* chunk_ = nullptr; + bool offsets_by_prx_ordinal_ = false; + std::vector pflat_; + std::vector poff_; +}; + // Streaming position cursor over one term's retained chunks.

Issue Number: N/A Related PR: #64909 Problem Summary: SNII phrase queries over high-df terms were CPU-bound in PFOR unpacking and docid conjunction ordinal mapping. PH5/PP5 profiling on the 10B cloud_sim dataset showed pfor_decode and intersect_window_candidate_range_with_ordinals as top self CPU consumers while remote bytes and serial read rounds stayed fixed. This change adds low-bit PFOR unpack fast paths for common widths 3/5/6/7 and a bounded-span bitset/rank intersection path that preserves PRX doc ordinals for 16K-doc windows. The optimized path keeps the on-disk format unchanged and reduces CPU in the cold cloud_sim phrase benchmark: PH5 BE CPU 48.07s -> 41.68s, PP5 BE CPU 49.95s -> 43.57s. ### Release note None ### Check List (For Author) - Test: Unit Test / Manual test - build-support/clang-format.sh be/src/storage/index/snii/core/src/encoding/pfor.cpp be/src/storage/index/snii/core/src/query/docid_conjunction.cpp be/test/storage/index/snii_query_test.cpp - build-support/check-format.sh be/src/storage/index/snii/core/src/encoding/pfor.cpp be/src/storage/index/snii/core/src/query/docid_conjunction.cpp be/test/storage/index/snii_query_test.cpp - git diff --check - build-support/run-clang-tidy.sh --build-dir be/build_Release - ./run-be-ut.sh --run --filter='SniiPhraseQueryTest.*:SniiTermQueryTest.*:SniiPrxPodTest.*:SniiPforTest.*' - ./build.sh --be -j 192 - cloud_sim deploy/start BE and PH5/PP5 cold phrase benchmark under /mnt/disk15/jiangkai/textbench/runs/20260628_phrase_cpu_opt_final_verified - Behavior changed: No - Does this need documentation: No --- .../index/snii/core/src/encoding/pfor.cpp | 305 ++++++++++++------ .../snii/core/src/query/docid_conjunction.cpp | 56 ++++ be/test/storage/index/snii_query_test.cpp | 56 +++- 3 files changed, 322 insertions(+), 95 deletions(-) diff --git a/be/src/storage/index/snii/core/src/encoding/pfor.cpp b/be/src/storage/index/snii/core/src/encoding/pfor.cpp index 98862d7f5ee8a9..5cdf8fdb57f9d6 100644 --- a/be/src/storage/index/snii/core/src/encoding/pfor.cpp +++ b/be/src/storage/index/snii/core/src/encoding/pfor.cpp @@ -35,28 +35,35 @@ uint8_t bits_for(uint32_t v) { // Exception cost estimated at ~6 bytes each. uint8_t choose_width(const uint32_t* v, size_t n) { uint8_t maxw = 0; - for (size_t i = 0; i < n; ++i) maxw = std::max(maxw, bits_for(v[i])); + for (size_t i = 0; i < n; ++i) { + maxw = std::max(maxw, bits_for(v[i])); + } uint8_t best = maxw; size_t best_cost = SIZE_MAX; - for (int w = 0; w <= maxw; ++w) { + for (uint8_t w = 0; w <= maxw; ++w) { size_t exc = 0; - for (size_t i = 0; i < n; ++i) - if (bits_for(v[i]) > w) ++exc; + for (size_t i = 0; i < n; ++i) { + if (bits_for(v[i]) > w) { + ++exc; + } + } size_t cost = (static_cast(w) * n + 7) / 8 + exc * 6; if (cost < best_cost) { best_cost = cost; - best = static_cast(w); + best = w; } } return best; } uint32_t low_mask(uint8_t w) { - return (w >= 32) ? 0xFFFFFFFFu : ((1u << w) - 1u); + return (w >= 32) ? 0xFFFFFFFFU : ((1U << w) - 1U); } void bitpack(const uint32_t* v, size_t n, uint8_t w, ByteSink* out) { - if (w == 0) return; + if (w == 0) { + return; + } uint64_t acc = 0; int filled = 0; for (size_t i = 0; i < n; ++i) { @@ -68,112 +75,218 @@ void bitpack(const uint32_t* v, size_t n, uint8_t w, ByteSink* out) { filled -= 8; } } - if (filled > 0) out->put_u8(static_cast(acc)); + if (filled > 0) { + out->put_u8(static_cast(acc)); + } } -Status bitunpack(ByteSource* src, size_t n, uint8_t w, uint32_t* out) { - if (w == 0) { - std::memset(out, 0, n * sizeof(uint32_t)); - return Status::OK(); +void bitunpack_tail(const uint8_t* base, size_t packed, size_t n, uint8_t w, size_t i, + uint64_t mask, uint32_t* out) { + for (; i < n; ++i) { + const size_t bit_off = static_cast(w) * i; + const size_t byte_off = bit_off >> 3; + uint64_t word = 0; + for (size_t b = byte_off; b < packed && b < byte_off + 8; ++b) { + word |= static_cast(base[b]) << ((b - byte_off) * 8); + } + out[i] = static_cast((word >> (bit_off & 7)) & mask); } - // Pull the whole packed run in ONE bounds-checked slice (#3: was one get_u8 - // per byte -- a Status-returning call + bounds check each), then unpack - // straight from the contiguous buffer.

This also made profile data unable to distinguish whether remote file-cache amplification came from segment metadata, dictionary, BSBF, posting, norms, or null bitmap reads. This change stores opened SNII logical index readers in the existing inverted-index searcher cache, keeps the owning IndexFileReader alive for the cached reader lifetime, registers logical section ranges before opening the reader, and propagates SNII section type through IOContext so profile counters can report physical remote bytes and file-cache block behavior by section. Add SNII inverted-index searcher cache support and SNII section-level file-cache profile counters. - Test: Manual test - Ran build-support/run_clang_format.py on changed BE files - Ran git diff --check and git diff --cached --check - Ran ninja -C be/build_Release -j192 doris_be - Deployed Release BE to cloud_sim and verified current-user MS/recycler/FE/BE processes plus SHOW BACKENDS Alive=true - Ran cloud_sim E2E SNII query/profile probes for cold Q4 and warm follow-up queries - Behavior changed: Yes. SNII format now reuses the inverted-index searcher cache for logical readers and exposes section-level profile counters. - Does this need documentation: No --- be/src/io/cache/block_file_cache_profile.cpp | 151 ++++++++++++++++++ be/src/io/cache/block_file_cache_profile.h | 32 ++++ be/src/io/cache/cached_remote_file_reader.cpp | 63 +++++++- be/src/io/cache/cached_remote_file_reader.h | 2 +- be/src/io/cache/file_cache_common.h | 9 ++ be/src/io/io_common.h | 39 +++++ be/src/snii/reader/logical_index_reader.h | 2 + be/src/snii/reader/snii_segment_reader.h | 3 + be/src/storage/index/index_file_reader.cpp | 26 ++- .../index/inverted/inverted_index_cache.h | 17 ++ .../core/src/reader/logical_index_reader.cpp | 8 + .../core/src/reader/snii_segment_reader.cpp | 16 ++ .../storage/index/snii/snii_doris_adapter.cpp | 83 +++++++++- .../storage/index/snii/snii_doris_adapter.h | 21 ++- .../storage/index/snii/snii_index_reader.cpp | 71 +++++++- be/src/storage/index/snii/snii_index_reader.h | 8 + 16 files changed, 530 insertions(+), 21 deletions(-) diff --git a/be/src/io/cache/block_file_cache_profile.cpp b/be/src/io/cache/block_file_cache_profile.cpp index ea3423c6a314b0..3d65b6ea7c1f04 100644 --- a/be/src/io/cache/block_file_cache_profile.cpp +++ b/be/src/io/cache/block_file_cache_profile.cpp @@ -17,6 +17,7 @@ #include "io/cache/block_file_cache_profile.h" +#include #include #include #include @@ -25,6 +26,22 @@ namespace doris::io { +namespace { + +constexpr std::array kSniiSectionNames { + "Unknown", "Meta", "Dict", "Posting", "Bsbf", "Norms", "NullBitmap"};

In cloud mode this made logical metadata requests appear as large physical remote reads and wrote metadata blocks into file cache. The SNII existence probe also opened a full logical index reader, which could read per-index metadata and small headers outside the searcher-cache lookup path. This change honors IOContext::read_file_cache=false in the cached remote reader, uses direct exact remote reads for SNII metadata scopes, opens SNII logical readers from owned per-index metadata bytes, and makes SNII index existence checks use the cached tail directory without materializing a LogicalIndexReader. LogicalIndexReader keeps per-index meta and small BSBF headers resident so searcher-cache hits avoid reopening metadata.

Issue Number: close #xxx Related PR: #xxx Problem Summary: SNII phrase-prefix with multiple tail expansions built a full phrase execution state for each tail term. That read complete tail docid and position postings before intersecting with the expected documents produced by the exact phrase prefix. The change reuses the docid conjunction planner with the expected docids as the initial candidate set, so tail expansions only fetch docid and PRX windows that can contain expected documents. The shared conjunction loop now covers both normal conjunctions and candidate-filtered conjunctions to avoid behavior drift. ### Release note None ### Check List (For Author) - Test: Unit Test / Manual test - Unit Test: ./run-be-ut.sh --run --filter='SniiPhraseQueryTest.MultiTailPhrasePrefixFiltersTailPrxByExpectedDocs:SniiPhraseQueryTest.WindowedPhrasePrefixQueryKeepsCorrectCandidateOrdinals:SniiPhraseQueryTest.SingleTailPhrasePrefixUsesStreamingPhrasePath:SniiPhraseQueryTest.MultiTermPhraseUsesPairPrefilter' -j "$(nproc)" - Manual test: ./build.sh --be -j "$(nproc)";

Issue Number: N/A Related PR: N/A Problem Summary: SNII two-term phrase queries still had to read and verify positional postings even when the query only needed an adjacent token pair. This was much slower than expected for common phrase predicates and made cold remote index scans expensive. This change writes filtered hidden phrase-bigram terms for SNII indexes with positions, uses them as a docid-only fast path for exact two-term MATCH_PHRASE, and filters hidden internal terms from prefix/wildcard/regexp expansion. Non-indexable phrase terms fall back to the existing positional path to preserve correctness. The SNII has_null path also reads per-index metadata through the resident segment reader instead of opening a logical index reader. ### Release note None ### Check List (For Author) - Test: Regression test / Unit Test / Manual test - BE unit test: ./run-be-ut.sh --run --filter='SniiSegmentReaderTest.*:SniiPhraseQueryTest.*:SniiTermQueryTest.*:InvertedIndexFileReaderTest.TestHasNullSnii*' -j $(nproc) - Build: ./build.sh --be -j $(nproc) - Regression test: ./bootstrap.sh run -- --run -d inverted_index_p0/storage_format -s test_storage_format_snii - Manual test: cloud_sim 10B phrase SNII load, full compaction, and cold query/profile benchmark against V3 - Behavior changed: No - Does this need documentation: No --- be/src/snii/format/phrase_bigram.h | 61 +++++++ be/src/storage/index/index_file_reader.cpp | 24 ++- .../snii/core/src/query/phrase_query.cpp | 48 +++++- .../snii/core/src/query/prefix_query.cpp | 17 +- .../snii/core/src/query/term_expansion.cpp | 4 + .../storage/index/snii/snii_index_writer.cpp | 72 ++++++++ be/src/storage/index/snii/snii_index_writer.h | 2 + be/test/storage/index/snii_query_test.cpp | 155 +++++++++++++++++- .../inverted_index_file_reader_test.cpp | 80 ++++++++- 9 files changed, 446 insertions(+), 17 deletions(-) create mode 100644 be/src/snii/format/phrase_bigram.h diff --git a/be/src/snii/format/phrase_bigram.h b/be/src/snii/format/phrase_bigram.h new file mode 100644 index 00000000000000..6c791da31fcb23 --- /dev/null +++ b/be/src/snii/format/phrase_bigram.h @@ -0,0 +1,61 @@ +#pragma once + +#include +#include +#include +#include + +namespace snii::format { + +inline constexpr std::string_view kPhraseBigramTermMarker = + "\x1F" + "SNII_PHRASE_BIGRAM" + "\x1F";

Issue Number: N/A Related PR: N/A Problem Summary: SNII meta reads explicitly disabled read_file_cache, so logical index metadata did not follow the query file-cache behavior used by the existing inverted index path. SNII section IOContext classification also treated non-meta sections as index data in some cases, which could put them into the file-cache index queue. This change lets SNII meta reads inherit the caller IOContext read_file_cache flag while keeping meta marked as index data, and routes every non-meta SNII section through normal file-cache queue classification. Unit tests cover the meta/non-meta IOContext routing. ### Release note None ### Check List (For Author) - Test: Unit Test / Static check - Unit Test: ./run-be-ut.sh --run --filter='DorisSniiFileReaderTest.*' -j "192" - Unit Test: ./run-be-ut.sh --run --filter='InvertedIndexFileReaderTest.TestHasNullSnii*' -j "192" - Static check: ./build-support/check-format.sh - Static check: ./build-support/run-clang-tidy.sh --build-dir be/ut_build_ASAN attempted; blocked by existing/toolchain issues: missing stddef.h, unmatched NOLINTEND in be/src/core/types.h, and existing IndexFileReader::_init_from function-size warning. - Behavior changed: Yes.

`be/src/snii/format/format_constants.h:14-16`）。一个容器内含多个 logical index，每个由交错的 posting region + DICT block region + per-index meta 组成。词查找链路为 BSBF bloom → SampledTermIndex → DICT block directory → 常驻/按需 DICT block → `DictBlockReader::find_term` → `DictEntry`。读路径经 `FileReader` 抽象（`be/src/snii/io/file_reader.h`）统一收口，本地文件与 S3 可互换；`BatchRangeFetcher`（`be/src/snii/io/batch_range_fetcher.h`）合并远程区间，生产路径由 `DorisSniiFileReader`（`be/src/storage/index/snii/snii_doris_adapter.cpp`）包装 Doris IO 栈。 + +本工作把一轮多智能体性能 review（48 条确认 finding，去重为 25 个任务、分 5 个批次）加一项并发/锁专项（T26）产品化。已接入 Doris 查询执行的算子面为：docid 过滤（term/match/any/all）、phrase、phrase-prefix、prefix、wildcard、regexp。 + +### 1.2 目标（Goals） +- 降低**已接入路径**（phrase/IO）的远程读放大：PRX 单轮批量读（T02）、adapter `read_batch` 并行去重排（T03）、DICT block 解压结果缓存（T04）。 +- 降低查询 CPU：regexp 用 RE2（T01）、≥3 词短语用 bigram 候选（T06）、key-first DICT 解码原语（T07）、wildcard 双指针（T08）等。 +- 降低构建吞吐/峰值内存：SPIMI 词表单份存储（T05）、PFOR `choose_width` 直方图（T11）、freqs 单遍统计（T12）等。 +- 消除解码路径微浪费：统一未初始化 resize 原语（T19）等。 +- **并发安全**：保证不引入"锁内 IO"或"粗锁串行化并发查询"的回归（T26、约束 T04/T07）。 +- 一处格式层优化（T18）在 launch 前完成。 + +### 1.3 非目标（Non-Goals） +- **不改变在盘格式**——除 T18 外，全部 25 个任务都是 reader/writer-only，前后兼容。 +- **不做 BM25 打分路径优化**：scoring 模块（`scoring_query_*`、WAND，`be/src/snii/query/scoring_query.h`/`bm25_scorer.h`）尚未接入 Doris 查询执行，相关 finding F04/F24/F45 全部 DEFER（见 §7）。 +- 不引入新的第三方依赖（RE2、Google Benchmark、libzstd 均已在 thirdparty）。 +- 不改变查询语义/结果集——所有改动须保持结果位级一致。 + +## 2. 任务分类与批次 + +| 批次 | 主题 | 任务 | +|---|---|---| +| Batch 1 | 远程读放大 + 并发 + RE2 | T01 RE2、T02 PRX 单轮批量、T03 adapter `read_batch` 并行、T04 DICT 解压缓存、T05 SPIMI

per-task plan 复用） + +### 3.1 (a) 未初始化/默认初始化 resize 原语（T19） +**问题**：解码缓冲普遍走 `out->resize(n)`（值初始化清零）随后被全量覆写——`be/src/storage/index/snii/core/src/encoding/zstd_codec.cpp:21`（`resize(expected_uncomp_len)` 后 `ZSTD_decompress` 全量写）、PFOR 解码缓冲、CSR offsets 等。清零是纯浪费。 + +**设计**：新增唯一头文件 `be/src/snii/common/uninitialized_buffer.h`，提供： +``` +namespace snii { template void resize_uninitialized(std::vector& v, size_t n); } +``` +对 trivially-copyable `T`，扩张部分**不做值初始化**；可用 default-init allocator 包装（`std::vector>` 的 typedef `RawBuffer`）或在受控处用 `resize` + 显式语义注释。**约束**：仅用于"resize 后立即被解码全量覆写"的缓冲；任何读取未写区间的路径禁止使用。所有现有 `resize`-then-overwrite 点（T19 列举：zstd/pfor/CSR/window framing）统一切换到该原语。**验证**：bit-identical 输出 + realloc/清零计数（见 3.5）。 + +### 3.2 (b) RE2 集成与 CMake 链接（T01） +**现状**：`regexp_query.cpp:3` 用 ``，`:77-87` 用 `std::regex`/`std::regex_match`（**全仓唯一** std::regex 使用点）。RE2 **已是 thirdparty target**：`be/cmake/thirdparty.cmake:57` `add_thirdparty(re2)` 已把 `re2` 追加进 `COMMON_THIRDPARTY` → `DORIS_DEPENDENCIES` → `DORIS_LINK_LIBS`（`be/CMakeLists.txt:589-609`），`libre2.a` 在 `thirdparty/installed/lib`，版本 `re2-2021-02-02`。 + +**设计**：T01 只需在 `regexp_query.cpp` 改用 `#include `、以 `RE2` 对象 + `RE2::FullMatch`（整词匹配语义，对齐现 `regex_match`）替换；编译期一次性构造、对 term 流式匹配。**CMake 通常无需新增**——`Storage` 经 `DORIS_LINK_LIBS` 传递链接 re2；若链接缺符号，则在 `be/src/storage/CMakeLists.txt:41-42` 给 `Storage` 显式 `target_link_libraries(Storage PRIVATE re2)`。须保留非法 pattern 的 `Status::InvalidArgument` 错误路径（RE2 用 `re2.ok()` 判定，不抛异常）。**验证**：非法 pattern 返回错误；与旧 std::regex 在一组黄金 pattern/term 上结果集逐字节一致；隐藏 bigram term 不外泄（已有用例 `snii_query_test.cpp:523-533`）。 + +### 3.3 (c) DICT-block 解压缓存设计与并发模型（T04，被 T07 复用） +**问题**：on-demand DICT block 解码到栈局部 `OnDemandDictBlock`（`be/src/snii/reader/logical_index_reader.h:124-130`；实现 `logical_index_reader.cpp` 的 `dict_block_reader_for_ordinal:143-159` → `open_dict_block` → `zstd_decompress`，约 64KB/块）。同一查询多词命中同一块时反复解压（F08/F20）。 + +**关键约束**：`LogicalIndexReader` 经 `InvertedIndexSearcherCache` **跨并发查询共享**（`snii_index_reader.cpp` `_get_logical_reader`），给它加可变缓存即引入共享可变状态。CONCURRENCY.md 隐患 1 明确：朴素实现（一把锁包住整张缓存且锁内做 ~64KB zstd 解压 + CRC）会同时犯"锁粒度过粗"+"锁内重活"，串行化最热的 term lookup。 + +**设计（两方案，红线统一）**： +- **方案 A（默认推荐）request-scoped（每查询）块缓存**：缓存随查询生命周期（挂在 per-query 上下文，如一个 `DictBlockCache*` 经 lookup/prefix 路径透传），**无共享可变状态、完全无锁**。解决"同查询多词反复解压"主因；跨查询复用交给 Doris page/file cache（字节级）+ searcher cache（小词典常驻）。 +- **方案 B（备选）分片 / lock-striped 缓存 + 锁外解压**：N 个 shard 按 block ordinal 哈希；shard 锁仅保护 map 查/插；**解压在锁外的局部缓冲完成后再插入**；并发 miss 容忍偶发重复解压（可选 single-flight 合并）。读者持 `shared_ptr` 在使用期无锁存活。 +- **红线（硬约束，写入 §4）**：**任何情况下不得在持任何锁期间执行 zstd 解压、CRC 或 `FileReader` IO。** + +T04 默认实现方案 A；方案 B 仅当确证需要跨查询块复用时启用，并须独立基准 + 通过 §4 全部并发不变量测试。**T07（key-first 解码原语）消费缓存**：解码后的 DICT block 暴露 key-first `find_term`（精确）+ 前缀流式 early-stop 扫描；块来自缓存还是新解码对 T07 透明。 + +### 3.4 (d) MOCK/COUNTING FileReader 测试骨架（T02/T03/T04/T26） +仓内**已有三套可复用骨架**，per-task plan 必须基于它们做确定性断言，禁止新造： +- **`MemoryFile`**（`be/test/storage/index/snii_query_test.cpp:53-101`）：同时实现 `snii::io::FileReader`+`FileWriter`，记录 `reads()`（每次 offset/len）、`read_bytes()`、`clear_reads()`。用于 snii 层 round-trip / 精确区间断言（已被 `:301-317`/`:471-483`/`:556-568` 等大量使用）。配套夹具 `build_reader()`（`:203-275`，9000 文档、`kDocsPositions`、含可选 phrase bigram）是 reader 侧标准 fixture。 +- **`RecordingFileReader`**（`be/test/storage/index/snii_doris_adapter_test.cpp:53-97`）：实现 Doris `io::FileReader::read_at_impl`，捕获 `CapturedRead{offset,len,io_ctx}`（含 IOContext 旗标 + `file_cache_stats`）。用于断言合并（`read_batch` → 1 次物理读，`:158-160`）与 IOContext 透传。 +- **`MeteredFileReader`**（`be/src/snii/io/metered_file_reader.h`）：模拟 1MiB-block FileCache，`metrics()` 返回 `IoMetrics{read_at_calls, serial_rounds, range_gets, remote_bytes, total_request_bytes}`，`reset_metrics()` 模拟冷缓存；`read_batch` 至多 1 个 serial round。是 serial-round / range-GET 的"标尺"。 + +**新增（本设计统一约定）**：在共享缓存/解压计数上引入一个 test seam——进程级原子计数器 `snii::testing::dict_decode_counter()`（在 `open_dict_block`/dict-block zstd 解码处自增，测试间可 reset）。它给 T04/T26 提供**确定性 decompress-count** 断言；FileReader 的 read-count 作旁证（非常驻块每解码对应一次 DICT 区读）。并发不变量验证（"解压锁外执行"）通过在解码入口断言"本缓存锁未被本线程持有"实现（计数=0）。 + +### 3.5 (e) 微基准 / 分配计数 / 位级黄金输出约定 +- **微基准（report-only，非 CI 门禁）**：复用 `be/benchmark` Google Benchmark 骨架——新增 `be/benchmark/benchmark_snii_*.hpp` 并在 `benchmark_main.cpp` `#include`。仅在 `-DBUILD_BENCHMARK=ON` 且 `CMAKE_BUILD_TYPE=RELEASE` 时编译为 `benchmark_test`（`be/CMakeLists.txt:1030-1038`，非 RELEASE 直接 `FATAL_ERROR`），默认关闭——故**绝不进 CI 门禁**。`QueryProfileScope`（`be/src/snii/query/query_profile.h`）提供 `elapsed_ns` + IO delta 供测内计时回退。 +- **分配/realloc 计数**：优先用 `vector::capacity()` 稳定性断言（reserve 一次、后续无 realloc → capacity 不变）；需要精确次数时用小型 `CountingAllocator` 注入受测缓冲。禁止全局 `new`/`delete` override。 +- **位级黄金输出**：纯重构/解码微优化任务（T13/T14/T19/T21/T22）的金标准是——捕获改前路径（或冻结 golden）输出字节，改后断言 `ByteSink::buffer()`/解码结果**逐字节相等**（仓内已普遍用解码相等模式，如 `snii_query_test.cpp:662-704`）。 + +## 4. 并发与锁设计原则（规范性，源自 CONCURRENCY.md） + +**现状（已读码确认，无需"修旧坑"）**：当前**没有锁内 IO，也没有粗锁串行化查询**。 +- `DorisSniiFileReader::_section_ranges_mutex`（`shared_mutex`，`snii_doris_adapter.h:98`）：`_classify_section`（`snii_doris_adapter.cpp:134-155`）持 `shared_lock` 仅内存扫描 ≤5 个 range，**返回即释放，IO 在锁外**（`read_at:166-180`、`read_batch:209-283` 均 classify→释放→`_read_at`）。`register_section_refs`（`:108-132`）持 `unique_lock` 仅 push ≤5 range，冷路径。非并发瓶颈。 +- `g_api_mu`（`s3_object_store.cpp:29`）：在 `#ifdef SNII_WITH_S3` 内、且该文件已被 `Storage` 构建排除（`be/src/storage/CMakeLists.txt:31`），仅护 `Aws::InitAPI` 引用计数，**非生产路径**。 +- 共享 `LogicalIndexReader` 读路径 const 无锁；on-demand 块解码到栈局部。安全。 + +**规范红线（所有任务必须遵守，重点约束 T04/T07/任何新增 per-reader 状态）**： +1. **NO-IO-UNDER-LOCK**：任何锁的临界区内禁止 `FileReader` IO、zstd 解压、CRC 等重活。把"分类（持锁）"与"IO（无锁）"在**代码结构上拆为独立函数**，便于单测断言。 +2. **共享 reader 缓存必须 request-scoped，或分片且解压在锁外**（§3.3 红线）。 +3. **reader-open miss 单飞（single-flight）**（隐患 2）：`_get_logical_reader` 在 cache miss 时直接 `open_snii_index`（meta+resident dict+BSBF 的 IO）再 insert，**无 in-flight 去重** → N 个并发 miss 同 index ⇒ N 次打开 IO。设计：对 `searcher_cache_key` 加 per-key in-flight map（`std::mutex` 仅护小 map + `std::shared_future`/`condition_variable`），首个 miss 占位后**在 in-flight 锁外执行打开 IO**，其余等待复用。**等待用条件变量/future，绝不持打开锁做 IO**。 + - **待确认项**：`InvertedIndexSearcherCache` 基于 Doris `LRUCachePolicy`（分片 LRU，`be/src/storage/index/inverted/inverted_index_cache.h:48-136`）——lookup/insert 各自线程安全，但 lookup→insert 之间非原子，**只去重 insert、不去重 open IO**。故 SNII 侧 single-flight 仍必要；T26 须先确证此语义再定实现。 + +**单体可验证（确定性，CI 可门禁）**： +- 锁内禁 IO 不变量：断言 IO 函数不接触 `_section_ranges_mutex`（结构分离 + mock read 回调探针）。 +- T04 缓存并发：N 线程并发 lookup → 断言（a）`dict_decode_counter()` == 唯一块数（方案 A）或 ≤ 唯一块数×分片冗余上界（方案 B）；（b）解码入口"缓存锁未持有"计数=0；（c）TSAN 干净。 +- single-flight：N 并发 miss 同 key → mock/计数 reader 断言底层 `open`/meta 读次数 == 1。 +- 吞吐：固定并发度 lookup QPS 改前后对比（report-only）。 + +## 5. 格式兼容策略 + +- **唯一格式变更：T18**（F11，prelude 窗口行裁剪可推导冗余字段）。其余 25 任务 reader/writer-only，零在盘变更，天然前后兼容，可任意顺序落地。 +- **当前版本锚点**：`kFormatVersion=2`、`kMetaFormatVersion=1`（`format_constants.h:16,24`）。`format_constants.h:18-23` 明确："pre-launch 只有一种 meta 布局 = v1，仅在 **launch 之后**、需与已写索引共存时才 bump；pre-launch 变更直接折叠进 v1"。 +- **T18 策略（pre-launch 优先）**：SNII 尚未 launch（无 `lifecycle: launched` 模块），T18 应**在 launch 前尽早落地**，直接折叠进 v1，**无需 bump、无需兼容 shim**——这是最省且符合设计意图的路径。 +- **兜底门控**：若 T18 有滑出 launch 窗口的风险，则**必须**二选一门控：(a) 新增 `frq_prelude` flag bit（`be/src/snii/format/frq_prelude.h:70-73` `frq_prelude_flags`）标记"trimmed prelude"，reader 双路兼容；或 (b) bump `kMetaFormatVersion` 到 2 并让 reader 同时处理 v1/v2。亦可走 `SectionType::kFeatureBits=9`（`format_constants.h:37`）作 feature 协商。 +- **铁律**：任何写 v1 之外字节的改动，未经上述门控不得合入。 + +## 6. 测试与验证基线 +所有任务遵循 TDD（RED→GREEN→REFACTOR），每个 plan 必含 `功能验证` 与 `性能验证（单体）` 两节（详见 conventions）。功能用例进 `be/test/storage/index/snii_*_test.cpp`（GLOB 自动纳入 `doris_be_test`，无需改 CMake）。性能优先确定性断言（fetch/open/decompress 计数、realloc 计数、位级一致、操作计数），wall-clock 仅 report-only。 + +## 7.

+- `_classify_section`（snii_doris_adapter.cpp:134-155）持 `std::shared_lock`（:141），仅在内存中线性扫描 ≤5 个 `SectionRange`，函数返回即释放（作用域在 :155 结束）。 +- `read_at`（:166-180）顺序：`_classify_section`（:170，锁内/锁外完成分类）→ 锁已释放 → `_read_at`（:175）做真正 IO（`_reader->read_at`，:198）。**IO 在锁外**。 +- `read_batch`（:209-283）同理：`_classify_section`（:265）→ 锁释放 → `_read_at`（:270）。**IO 在锁外**。 +- `register_section_refs`（:108-132）持 `std::unique_lock`（:126）仅 `push_back` ≤5 个 range，无 IO，且只在 index open 时调用一次（冷路径）。 +- `shared_mutex` ⇒ 并发读（classify）不互斥；唯一互斥是 register(写) vs classify(读)，register 冷，可忽略。 +- 结论：**不是并发瓶颈**（与第一轮 review 的 R9/R10 被判低影响一致）。唯一微小成本是每次物理读前一次 shared_lock 的原子获取/释放，但远小于其后的 IO，且读并发。 + +### 2) `s3_object_store.cpp` 全局 `std::mutex g_api_mu`（:29） +- 位于 `#ifdef SNII_WITH_S3`（:6）内——standalone/bench 路径，**非 Doris 生产路径**（生产经 `DorisSniiFileReader::_reader->read_at`，即 Doris 自己的 IO/S3 栈）。 +- 只保护 `Aws::InitAPI/ShutdownAPI` 的进程级引用计数（`api_acquire`/`api_release`，:33-49），**不保护 GetObject**。即便 standalone 也不是锁内 IO。 +- 结论：**非生产并发问题**。仅需一行备注：若将来 standalone S3 store 进入生产，需复审。 + +### 3) 跨查询共享的 `LogicalIndexReader`（经 `InvertedIndexSearcherCache` 缓存，snii_index_reader.cpp:343-346） +- 读路径目前**无锁只读**：`lookup()` 为 const；常驻 dict block / BSBF bitset 在 open 后不可变；on-demand dict block 解码到**栈局部** `OnDemandDictBlock`（logical_index_reader.h:124-130）。 +- 结论：并发安全且不互斥；代价是重复 IO/解压（性能 findings F08/F20），**不是锁问题**。 + +→ **回答“当前并发/锁机制有没有问题”：没有锁内 IO、没有粗锁串行化查询的问题。** 但存在以下两个并发隐患。 + +## 二、隐患 1（最关键，属“将来自己挖的坑”）：T04 的 dict-block MRU 缓存会引入并发回归 + +`LogicalIndexReader` 跨查询共享，给它加可变缓存 = 引入共享可变状态。若 naive 实现（一把 `std::mutex` 包住整个缓存，且在 miss 时**锁内执行 ~64KB zstd 解压 + CRC**），就同时犯了： +- **锁粒度过粗**：串行化所有并发 term lookup（最热路径）。 +- **锁内做重活**：解压/CRC 在临界区内，等价于“锁内 IO”级别的阻塞。 +并发吞吐会显著下降——这正是用户担心的两点。 + +### 设计红线（必须写入总设计文档，硬约束 T04 / T07 / 任何新增 per-reader 缓存） +- 方案 A（推荐之一）：**request-scoped（每查询）块缓存** —— 彻底消除共享可变状态、无锁；解决“同一查询多词命中同一 block 反复解压”这一主因；跨查询复用交给 Doris page/file cache + searcher cache。 +- 方案 B：**分片 / lock-striped 缓存 + 锁外解压** —— 锁只保护 map 的查/插；解压在锁外的局部缓冲完成后再插入；并发 miss 容忍偶发重复解压（可选 single-flight 合并）。 +- **红线：任何情况下不得在持锁期间执行 zstd 解压、CRC 或 FileReader IO。** + +## 三、隐患 2（现存）：冷启动 / 缓存淘汰时 reader 重复打开（thundering herd） + +`_get_logical_reader`（snii_index_reader.cpp:329-346）在 cache miss 时直接 `open_snii_index`（:334，执行 meta + resident dict + BSBF 的 IO）然后 insert，**无 in-flight 去重（single-flight）**。N 个并发 miss 同一 index ⇒ N 次打开 IO，N-1 次 insert 浪费。高 QPS + 冷缓存 / 淘汰风暴时拖并发。 + +### 修复方向 +- 对 `searcher_cache_key` 做 single-flight：per-key in-flight map（`mutex` + `condition_variable`/`shared_future`），首个 miss 打开、其余等待复用。**注意：single-flight 的等待用条件变量，绝不在持有打开锁时做 IO 之外的阻塞；打开 IO 本身在 in-flight 占位之后、全局锁之外执行。** +- 或先确认 `InvertedIndexSearcherCache::lookup/insert`（Doris 侧）的并发语义：是否分片锁、是否对并发同 key 的 insert/open 去重。若仅去重 insert 而 open 仍各自发生，则仍需 SNII 侧 in-flight 合并。 + +## 四、待确认项 +- `InvertedIndexSearcherCache`（storage/index/inverted/inverted_index_cache.h）的 lookup/insert 并发语义（分片锁？同 key 并发 insert 去重？）——决定隐患 2 是否需要 SNII 侧 single-flight。 + +## 五、单体可验证的并发测试要点（供 T26 / T04 复用） +1. **“锁内禁 IO”结构性不变量**：将“分类（持锁）”与“IO（无锁）”在代码结构上分离为独立函数；单测断言 IO 函数不接触 `_section_ranges_mutex`。或在 mock FileReader 的 read 回调中通过探针断言 `_section_ranges_mutex` 未被本对象持有。 +2. **T04 缓存并发（确定性）**：N 线程并发 lookup —— 断言（a）解压次数 == 唯一 block 数（request-scoped）或 ≤ 唯一 block 数 ×(分片冗余上界)（分片方案）；（b）在解压函数入口断言“本缓存锁未被持有”（锁外解压不变量，计数器=0）；（c）TSAN 无数据竞争。 +3. **single-flight（确定性）**：N 并发 miss 同 key —— 用 mock/计数 FileReader 断言底层 `open`/meta 读次数 == 1。 +4. 吞吐（report-only，非 CI 门禁）：固定并发度下的 lookup QPS，对比加缓存前后，确认无并发回归。 diff --git

PRX 阶段从「每 term 一个 fetcher + 一次 `fetch()`」重构为「整个短语共享一个 `BatchRangeFetcher`，两遍式：pass1 建 chunk 并 `add()` 所有 PRX range（记录回填句柄），单次 `fetch()`，pass2 回填 `chunk.prx` Slice」。 + +新增文件内辅助结构： +```cpp +struct PrxRangeAssignment { + size_t plan_index; // index into srcs + size_t chunk_index; // index within srcs[plan_index].chunks + size_t handle; // handle into the shared fetcher +}; +``` + +builder 改签名（去掉私建 fetcher，改为接收共享 fetcher + 装配记录 + plan_index）： +```cpp +Status BuildFlatPositionSource(idx, round1, doc_source, p, candidates, + size_t plan_index, + snii::io::BatchRangeFetcher* prx_fetcher, +

(poff,plen)，`prx_fetcher->add(poff,plen)` 取 handle；按现逻辑构造 chunk（dd 仍从 round1 解码、`SelectCandidateDocsForPrx` 仍只对 docids 运算，不依赖 prx 字节）；仅当 chunk 被 push 时记录 `assignments.push_back({plan_index, chunk_index_before_push, handle})`。**为保持与现实现字节等价**：现实现对每个 pod_ref term 无条件 `fetch()`（即便 chunk 最终为空），故 `add()` 同样无条件执行；chunk 为空时只是不记录 assignment（多读的字节与现行为一致）。 +- flat inline（`!p.pod_ref`）：保持 `chunk.prx = Slice(p.entry.prx_bytes)`，**不 add 任何 range**（保留 `:310` 零 IO 快路径）。 +- windowed：保留 `ChunkMayContainCandidate` 过滤、`SelectCandidateDocsForPrx`、`windowed_window_range`；把现有 `prx_fetcher->add(range.prx_off, range.prx_len)` 改为对共享 fetcher 调用，`chunk_index = src->chunks.size()`（push 前），记录 `assignments`，删除本函数内的 `fetch()`/get/owners-push。 + +**两遍顺序正确性**：候选选择（`SelectCandidateDocsForPrx` / `docids_are_final_candidates` 分支）决定 candidate 落在哪个 window，必须先于 range 计算——pass1 内部即按此顺序（先 select 再 `windowed_window_range` 再 add），与现实现完全一致。所有 range 计算只读 prelude（round1 已 open）与 docids，**不读 prx 字节**，故可全部先 `add` 再统一 `fetch`。 + +**coalesce_gap 选择**：共享 fetcher 用 `kSameTermCoalesceGap`（=16KB，与现 windowed 路径一致）。验证器纠正：保留 same-term 窗口内合并；跨 term 的 PRX span 在 posting region 中相距甚远（各 term 为 [prx][frq] 连续大段），不会过度合并到把中间 frq 读进来；批量收益来自 `read_batch` 的波内并发，而非合并。**不得**为强制跨 term 合并而抬高 gap（会过读 term 间的 frq）。flat 路径原 gap=0、每 term 仅一个 prx range（单 range 无可合并内容），并入共享 fetcher 后即便相邻 term 的 prx 落入 16KB 内被合并，`get()` 经 `sub_offset` 仍返回正确子切片，最多多读 ≤gap 字节，正确性不受影响。 + +**FORMAT-COMPATIBILITY**：reader/writer-only，零在盘变更。PRX offset 经 `resolve_prx_window`/`windowed_window_range` 与现实现逐字节同算。 + +**CONCURRENCY**：N/A，无共享可变状态。共享 fetcher 是 **request-scoped**（生命期挂在 `PhraseExecutionState::owners` 或 tail 路径局部 `owners`），单线程顺序使用；`get()` 返回的 Slice 指向 `phys_` 缓冲，`fetch()` 后稳定，与现「每 term fetcher 保活」语义相同。并发只发生在 `read_batch` 内部（S3 `std::async` 波），fetcher 本身不跨线程。共享 `LogicalIndexReader` 读路径仍为 const 无锁；本改动不新增任何 per-reader 可变状态，无 NO-IO-UNDER-LOCK 风险（无锁）。 + +### 4. 依赖 + +- depends_on：无（Batch 1 独立）。 +- 复用既有基础设施：`BatchRangeFetcher`（已存在 `add/fetch/get/pending` 语义恰好支持两遍式）；测试侧

PhraseQueryIssuesSinglePrxBatchRound)`：包 `BatchRoundCountingReader`，跑 3-term `phrase_query`，断言 `reader.batch_rounds() == 2`（round1 一次 + PRX 阶段一次；conjunction 对 flat term 0 次）。**当前代码该值为 4**（PRX 阶段每 term

声明为 `std::unordered_map`（`spimi_term_buffer.h:306`，默认 `std::hash`/`std::equal_to`，无 `is_transparent`），所以用 `string_view` 探测必须先把它物化成 `std::string`。对 >SSO（15B）的 term（每个 phrase bigram 至少 20B marker，见 `phrase_bigram.h:10-13`，实测 marker = 20 字节；CJK/长 token 亦然）这是 per-token 的 malloc+memcpy+free。该开销对"已见 term"的常态命中也照付（`find` 总要先建探测键）。 +- **F03 [HIGH]**：每个 distinct term 字符串被存两份。`spimi_term_buffer.cpp:226-228`：`owned_vocab_.emplace_back(term)` 存第 1 份，`intern_.emplace(owned_vocab_.back(), term_id)` 把字符串作为 map key 再拷一份（第 2 份 owned `std::string`），加上 unordered_map 节点开销（~16B 节点 + 4B value）。对 phrase-bigram/高基数列（数百万 distinct bigram）这是数百 MB 的可避免重复，且全程不可 spill（`spill_to_run`/`merge_runs` 只释放 arena 与 slot，见 `:476`、`:522-524`；`resident_bytes()` `:96-103` 也不计 vocab），是

`string_view` 异构探测，零临时串、零 malloc；F03 —— set 只存 4B id，字符串只在 `owned_vocab_` 存一份，map 的 owned-string key 彻底消失。 +- **C++20 支持**：BE 为 C++20（`be/CMakeLists.txt:350`），P0919/P1690 为 unordered 容器提供异构 `find`，要求 **hash 与 equal 都透明**（两者都加 `using is_transparent = void;`，缺一不可 —— F21/F03 验证器均明确强调）。hash 始终以 `string_view` 计算，保证 stored-id 与 probe-string_view 对相同内容产生相同 hash，已有条目可被找到。 + +### 3.2 add_token(string_view)

指针稳定性（关键正确性论证） + +set **存的是 id（值类型 uint32_t），不存指针/`string_view`**。因此 `owned_vocab_.emplace_back` 触发的 vector 扩容**不会**使任何已存条目失效：扩容后 hash/eq 仍按当前 `owned_vocab_[id]` 重新读取内容。这正是为何无需把 `owned_vocab_` 换成 pointer-stable 容器，从而完整规避 F03 验证器 caveat 1/2。插入顺序：先 `emplace_back`（使 `owned_vocab_[term_id]` 有效），再 `insert(term_id)`（其 hash 解引用该项）—— 顺序正确。 + +### 3.4 构造期绑定 + +owned-vocab 构造函数（`cpp:62-70`）体内把 `intern_`

前即 reject，functor 永不被解引用）。成员声明顺序 `owned_vocab_`(304) 先于 `intern_`(306)，构造体内绑定与声明序无冲突。 + +### 3.5 FORMAT-COMPATIBILITY 结论 + +**reader/writer-only，零在盘字节变更。** `intern_`/`owned_vocab_` 纯内存构建态；run 以

vocab**（F03 验证器 caveat 4）：本任务**刻意不改** `resident_bytes()`（`:96-103`），避免 vocab 单独超 cap 导致 `over_cap` 永久 latch、每 token 病态 spill。该缺口列入 gaps，留待后续以独立 observability 指标处理。 +6. **计数 seam 的生产开销**：最终态仅在

与构造函数三处，且零在盘格式变更、零接口签名变更（`vocab()`/`MergeRuns` 不动）。`git revert` 该提交即可完全恢复旧 `unordered_map` 路径，无数据迁移、无兼容性后果；新建测试文件可独立保留或一并撤回。 \ No newline at end of file diff --git

检查（任一词缺失→空，短语必不匹配）。 +2. `phrase_bigram_enabled(idx,&enabled)`。 +3. `ShouldUsePhraseBigram`: 返回 true 当且仅当 (a) `enabled`（sentinel 存在=较新索引，**格式兼容门**），且 (b) 所有 `terms[i]` 满足 `is_phrase_bigram_indexable_term`（与 writer 仅对可索引词建相邻 pair 的语义对齐，见 `snii_index_writer.cpp:118-120`），且 (c) **至少一个 plan 为 windowed**（df>=512；对应验证器 caveat(5)：全稀疏词时 per-term 交集已极小，读 n-1 个 bigram 反而可能略差，故回退）。 +4. 若不启用 → 走原 `ExecutePhrasePlans(... , initial_candidates=nullptr)`（与今日完全一致的回退路径）。 +5. 若启用 → `BuildBigramPhraseCandidates`： + - 由**原始有序 terms**构造相邻 pair `(terms[i],terms[i+1]), i∈[0,n-2)`（**用有序 terms 而非 unique_terms**，正确处理重复/重叠词，验证器 caveat(3)）。 + - 对每个 pair `resolve_query_term(make_phrase_bigram_term(...))`。若某 pair **未找到**：因 sentinel 已启用且两词均可索引，writer 必然会为任何曾相邻连续出现的 pair 建 bigram，故「未找到 ⟺ 该 pair 从未连续出现 ⟺ 短语必不匹配」→ `candidates` 置空、`usable=true` 返回（验证器 caveat(2) 的 df=0 早空等价）。 + - 全部命中 → 收集 `ResolvedDocidPosting`，`read_docid_postings_batched` 一轮取所有 bigram docid，`intersect_sorted` 折叠求交 → `candidates`（短语匹配的严格超集）。 +6. `if (usable && candidates.empty()) return OK();` +7. `ExecutePhrasePlans(idx,&round1,&plans,mapping.phrase_plan_index,docids, usable ? &candidates : nullptr)`。 + +**为何结果不变（正确性核心）**: 若短语在某 doc 的位置 p..p+n-1 出现，则每个相邻 pair 的 bigram 在该 doc 必存在 → 该 doc ∈ 所有 bigram posting 的交集 → ∈ candidates。故 candidates ⊇ 真匹配集；随后的 `BuildPhraseExecutionState(initial=candidates)`→`filter_docids_by_conjunction`→`BuildPositionSourcesForCandidates`→`EmitPhraseStreaming` 为**完全未改动**的精确位置校验，输出与旧路径逐位相等（两个 bigram 同现不证明它们链式相接，故校验仍必需——验证器明确指出）。 + +**`BuildPhraseExecutionState` 改造**: 形参增 `const std::vector* initial_candidates`。`initial_candidates==nullptr` → 原 `build_docid_only_conjunction(idx,*round1,*plans,&state->candidates,&doc_sources)`；否则 → `filter_docids_by_conjunction(idx,*round1,*plans,*initial_candidates,&state->candidates,&doc_sources)`（范式同 `:1115`）。其余（`round1->fetch`、`open_preludes(need_positions=true)`、`BuildPositionSourcesForCandidates`）不变。 + +**FORMAT-COMPATIBILITY**: reader/writer-only，零在盘变更。bigram posting（含左词位置）与 sentinel 均由现行

的解码）每个字节都付出一次跨翻译单元（TU）的非内联函数调用 + 分支 + 两级 `vector>` 指针追逐。 + +- 编码侧热点：`snii_index_writer.cpp:153/178/250` 每 token 调 `add_token` → `SpimiTermBuffer::accumulate`（`spimi_term_buffer.cpp:139`）→ `put_varint`（`:133`）→ `put_byte`（`:128-131`）→ `pool_.append_byte`（定义在 `compact_posting_pool.cpp:97`，out-of-line）。每个 payload 字节一次跨 TU 调用。 +- 解码侧热点：finalize 时 `to_postings`（`spimi_term_buffer.cpp:323`）→ `DecodeChainVarint`（`:298-308`）→ `Cursor::next()`（定义在 `compact_posting_pool.cpp:129`，out-of-line）。每个 arena 字节一次跨 TU 调用 + `cur_==slice_end_` 分支 + budget 检查。 + +**根因（验证器已独立确认）**：`append_byte`（`compact_posting_pool.cpp:97`）、`Cursor::has_next`（`:120`）、`Cursor::next`（`:129`）的函数体定义在 `.cpp`，调用方在另一个 TU（`spimi_term_buffer.cpp`）。`be/CMakeLists.txt` 与 `cmake/` 无 `-flto`/`INTERPROCEDURAL_OPTIMIZATION`、无 unity build（已 grep 确认无命中），所以两文件是真正独立 TU，无跨 TU 内联。`at()` 虽是 header-inline（`compact_posting_pool.h:158-159`，能折进 `.cpp` 内的函数体），但调用边界本身无法消除。 + +**预期收益**：把三个热点小函数体移入头文件 `inline`，让调用方所在 TU 直接内联，编译器得以在 LEB128 内层循环里把 `cur_/slice_end_/budget_` 保活在寄存器、消除 call/ret 与栈传参。finder 估 ~10-25% off arena encode/decode CPU；验证器纠正：该百分比**仅适用于 arena 编解码微循环**，decode 侧（纯解码、无与 tokenization 重叠）是更可信的一半；整建 CPU 由 tokenization/PFOR/zstd 主导，'helps build' 夸大整建影响。本任务定位为**作用域明确的微优化**，行为完全不变。 + +--- + +## 2. 影响的文件/函数 + +只动 writer 构建侧两文件中的一个（头）： + +- `be/src/snii/writer/compact_posting_pool.h` + - `void CompactPostingPool::append_byte(SliceWriter* w, uint8_t* level, uint8_t value);`（声明 `:92`）— 函数体将从 `.cpp` 移入头作 `inline`。 + - `bool CompactPostingPool::Cursor::has_next() const;`（声明 `:135`）— 同上。 + - `uint8_t CompactPostingPool::Cursor::next();`（声明 `:138`）— 同上。 + - 私有成员（已在头声明，inline

`.cpp`）：`alloc_run`（`:39`）、`alloc_slice`（`:71`）、`read_ptr`（`:80`）、`write_ptr`（`:86`）、`start_chain`（`:90`）、`reset`、静态数组定义（`:14-17`）、`CompactPostingPool()`、`kSliceSize*_at`。 + +调用方 `be/src/storage/index/snii/core/src/writer/spimi_term_buffer.cpp` **不改动**（`put_byte` `:128`、`DecodeChainVarint` `:298` 保持原样，仅因头内联而获益）。 + +--- + +## 3. 变更设计 + +**具体改动（纯代码搬移，机械安全）**：在 `compact_posting_pool.h` 的 class 定义**之后、namespace 关闭之前**，新增三个 `inline` 函数定义（搬移原 `.cpp` 函数体，逐字不改逻辑）。放在 class 完整定义之后可保证所有私有成员（`at`、`read_ptr`、`write_ptr`、`alloc_slice`、`kSliceSizes`、`kNextLevel`）此时均已声明可见，避免「类内引用尚未声明的成员」问题。`Cursor` 是 `CompactPostingPool` 的嵌套类，可合法访问外层私有 `at()`/`read_ptr`。 + +签名不变，三函数体一字不动地搬移： +```cpp +inline void CompactPostingPool::append_byte(SliceWriter* w, uint8_t* level, uint8_t value) { /* 原 :97-112 */ } +inline bool CompactPostingPool::Cursor::has_next() const { /* 原 :120-127 */ } +inline uint8_t CompactPostingPool::Cursor::next() { /* 原 :129-153 */ } +``` + +**ODR / 链接结论（验证器确认）**：静态 `const uint32_t kSliceSizes[]` / `const uint8_t kNextLevel[]` 在头声明（`:155-156`）、唯一 out-of-line 定义在 `.cpp`（`:14-17`），具外部链接；inline 头函数引用它们在链接期解析，无 ODR 问题。`alloc_slice`/`write_ptr` 仍在 `.cpp`，inline 的 `append_byte` 只在冷的 slice-overflow 分支调用它们——热的每字节工作（`at()`、`++cur`、`++payload_bytes_/--budget_`）内联，冷 helper 留 `.cpp`。 + +**FORMAT-COMPATIBILITY 结论**：reader/writer-only，**零在盘变更**。`CompactPostingPool` 是纯内存累加 arena，其 slice-chain 编码是内部表示，drain 时被解码为 `TermPostings` 后再由 writer 用 PFOR/varint

TDD 实施步骤 + +本任务是**行为保持的纯重构（代码搬移）**。按项目 §8「纯重构/解码任务断言改前后逐字节相等」执行；由于 `CompactPostingPool` 当前**零单测覆盖**（已 grep 确认 `be/test` 无任何 `CompactPostingPool`/`SpimiTermBuffer` 引用），RED→GREEN 同时为该 arena 落地首份回归网。 +

gather 循环 `vocab[heap.top().term_id] == merged.term`（`spill_run_codec.cpp:459`）。 + +由于 vocab 在所有 run 间**共享且稠密**（同一 term 在每个 run 里 term_id 相同），这些比较本可纯整数化。该路径在生产真实触发：accumulator 超过 gate-2 cap 即 spill 成 K 个 run 并经 `merge_runs`→`MergeRuns`（`spimi_term_buffer.cpp:530`）。堆做 O(N log K) 次比较（N = 跨 run 的 term 条目总数，大段可达数百万；K 通常个位到低两位数），每次比较随机索引 `std::vector`（32 B/slot）并 length+memcmp。 + +**已有的复用基础**：`string_rank_`（term-id → 全词典字典序 rank，4 B/id 稠密数组）已经在 spill 路径上被构建——每次 spill 经 `drain_to_writer`→`sorted_ids()`→`ensure_string_rank()`（`spimi_term_buffer.cpp:402-424`），声明为 `mutable`（`spimi_term_buffer.h:355-359`）。作者已在 `sorted_ids()`（`spimi_term_buffer.cpp:415-424`）用同一技术把每次 spill 的 id 排序从 strcmp 改成整数 rank 比较。 + +**预期收益**：把归并内层循环里所有「随机 vocab 字符串访问 + 字节比较」改为「稠密 4 B

容量在构造时固定（`spimi_term_buffer.cpp:56` 用 `assign(vocab_size,0)`，此后只 `[]` 写入，capacity 不再增长）。**绝大多数 token 的 delta 为 0**，却仍付出一次锁前缀 `fetch_add(0)`。 + +**期望收益**：消除热路径上几乎全部 per-token 原子 RMW（arena 约每 32 KiB 才增长一次），把 `report()` 调用从 O(token 数) 降到 O(arena 增长事件数)。验证器修正：墙钟收益是真实但很小的（远小于 build CPU 1%），且 Doris 下 `consume_release==null`，被省掉的仅是一次原子加；因此本任务的价值定位为"消除热路径上确定可计数的多余原子写"，用**确定性 op-count** 验证，而非墙钟。 + +**验证器关键纠正（必须遵守）**： +- 修复**只**做"delta==0 时跳过 `report()`"这一半。`report_arena_delta()` 内 early-return 即可，字节等价、线程安全、零在盘影响。 +- **禁止**修复的第二半（把 `over_cap()` 用本 buffer 的 arena delta 来 gate 或缓存其结果）。`over_cap()` 读的是 **writer 级 UNIFIED 总量**，与 dict buffer 共享同一个 `mem_reporter`（`logical_index_writer.cpp:351` 用同一 reporter 构造 `dict_buf_`；`memory_reporter.h:38-42` 注明 unified total = arena + slot index + dict）。dict 侧增长可在本 buffer delta==0 时把总量推过 cap；gate 掉就会漏掉 spill 触发。且 `over_cap()` 只是 relaxed load+compare（无锁前缀），便宜，无需 gate。**每个 token 仍无条件调用 `over_cap()`**。 + +## 2. 影响的文件/函数 + +**唯一实现改动**：`be/src/storage/index/snii/core/src/writer/spimi_term_buffer.cpp` + +当前签名/实现（`:83-90`）： +```cpp +void SpimiTermBuffer::report_arena_delta() { + if (mem_reporter_ == nullptr) return; + const int64_t now = static_cast(resident_bytes()); + mem_reporter_->report(now - reported_resident_); // 无条件 fetch_add(可能为 0) + reported_resident_ = now; +} +``` + +调用点（均经此函数，无需逐点改）：`:59`（ctor 报告 slot_of 初值）、`:180`（accumulate 热路径）、`:458`（drain_sorted 末尾负值）、`:480`（drain_to_writer spill 后负值）、`:529`（merge_runs 释放 slot_of 负值）。后三处报告的都是**非零负 delta**（释放），early-return 不影响；`:180` 是受益点。 + +**不改**：`memory_reporter.h`（`report()`/`over_cap()` 语义不动）、`accumulate()` 内 `over_cap` 分支（`:187-189`，保持每 token 无条件求值）、`spimi_term_buffer.h`（无签名变更）。 + +## 3. 变更设计 + +**改动（极小）**：在 `report_arena_delta()` 计算 `now` 后，若 `now == reported_resident_`（即 delta==0）直接返回，跳过 `report()` 与 `reported_resident_` 赋值： + +```cpp +void SpimiTermBuffer::report_arena_delta() { + if (mem_reporter_ == nullptr) return; + const int64_t now = static_cast(resident_bytes()); + if (now == reported_resident_) return; // skip the per-token zero-delta locked fetch_add + mem_reporter_->report(now - reported_resident_); + reported_resident_ = now; +} +``` + +**语义等价性论证**：被跳过的调用 delta 恒为 0。`current_.fetch_add(0)` 对原子值无效果；`consume_release(0)`（Doris 下为 null）若存在也是镜像 0；delta==0 时 `now==reported_resident_`，不更新

`ByteSink`，payload 只拷一次（即流式 sink 那次）。 + +`write_pfor` 改写为： +```cpp +void write_pfor(Slice payload, ByteSink* sink) { + const size_t start = sink->size(); + sink->put_u8(static_cast(PrxCodec::kPfor)); + sink->put_varint32(static_cast(payload.size())); + sink->put_bytes(payload); + const size_t framed_len = sink->size() - start; + const uint32_t crc = crc32c(sink->view().subslice(start,

的 `view()` 必须在写完 payload **之后、写 crc 之前**取——此刻 `buf_` 连续、无后续插入，`subslice(start, framed_len)` 指向的内存有效，无 realloc/aliasing 隐患。 +- crc 覆盖的字节范围 = `[codec/type][varint len][payload]`，与 reader（`read_framed` `prx_pod.cpp:612-638` / `SectionFramer::read`）重新推导的 `slice_from(start, framed_len)` 完全一致，故 CRC 值不变。 +- `put_fixed32` 写的是 4 字节小端（`byte_sink.cpp:11-13`），与原 `sink->put_fixed32(crc32c(framed.view()))` 字节一致。 + +### 3.2 emit_region raw 分支去临时 vector（F38） + +raw 分支不再构造 `disk`，直接用 `plain`： +```cpp +Status emit_region(Slice plain, int level, ByteSink* out, FrqRegionMeta* meta) { + if (out == nullptr ||

out->put_bytes(plain); + return Status::OK(); +} +``` +**正确性点**：reader 侧 `open_region`（`frq_pod.cpp:97-121`）对 raw 区强校验 `uncomp_len == disk_len` 且 `crc32c(disk) == meta.crc`；因 raw 上盘字节逐字节等于 `plain`，`disk_len = plain.size()`、`crc = crc32c(plain)` 保持不变量成立。`plain`（来自 `ByteSink::view()`，连续）满足 `crc32c(Slice)`/`put_bytes(Slice)`。 + +### 3.3 bitpack 去逐字节 push_back（F32 子项） + +`bitpack` 在循环前按精确字节数预留，消除 realloc 抖动（验证器纠正：`reserve` 取**绝对容量 size()+needed**，否则缓冲增长后再 reserve 同值即 no-op，因为 `encode_pfor_runs` 复用同一 `out` 跨多个 run）。两个 run 编码器（`prx_pod.cpp:104` / `frq_pod.cpp:36`）run 长度恒 `<= kFrqBaseUnit=256`，w<=32 → packed `<= (32*256+7)/8 = 1024` 字节，故可用栈缓冲一次 `put_bytes`： +```cpp +void bitpack(const uint32_t* v, size_t n, uint8_t w, ByteSink* out) { + if (w == 0) return; + const size_t packed = (static_cast(w) * n + 7) / 8; + out->reserve(packed); // 新增 ByteSink::reserve(additional) + // 仍逐字节填，但已无 realloc；保留原 acc/filled 位拼装逻辑，字节完全一致 + ... +} +``` +为兼容未来可能的大 n 直接调用，采用 `reserve(packed)`（通用、简单、必然位级一致）作为主方案；栈缓冲 + 单次 `put_bytes` 作为可选优化（需 `packed <= 栈上限` 的运行时回退）。本计划落地 `reserve` 方案。`ByteSink::reserve`： +```cpp +void reserve(size_t additional) { buf_.reserve(buf_.size() + additional); } +``` + +### FORMAT-COMPATIBILITY 结论 +**reader/writer-only，零在盘变更**。三处 framing、emit_region raw、bitpack 均产出与改前**逐字节相同**的 on-disk 字节与 CRC（§3 各点已逐一论证 crc 覆盖范围/长度不变）。 + +### CONCURRENCY 结论 +**N/A，无共享可变状态**。全部改动位于单线程 build 路径；`ByteSink` 是函数局部对象，`emit_region`/`bitpack` 仅操作入参 `Slice` 与调用方私有 sink。不触及共享 `LogicalIndexReader`、不在任何锁临界区内、不涉及 IO/解压（NO-IO-UNDER-LOCK 红线无关）。 + +## 4. 依赖 + +-

边界（不变），把该段 memcpy 进 `window_region_`；据 `rows` 填 `sb_spans_`、`sb_last_docid_`、`n_super_`、`n_windows_=h.n`；`sb_cache_/sb_decoded_` 按 n_super_ 置空。 +4. **派生块长**：若

`positioned.reserve+push_back` 构造临时向量并 `std::ranges::sort`（主键 position uint32、次键 term）。但 analyzer 产出的 token position 单调非降（`analyzer.cpp` `position += token.getPositionIncrement()`，increment≥0），`position_base` 为均匀常量偏移，因此 `positioned` 入栈即有序；次键 term 对发出的 bigram 集合无影响（窗口循环 `:157-163` 对每个 left×right 对全量发出，且 `SpimiTermBuffer::add_token` 按 term 去重、按 docid/pos 累加、finish 时统一定序，发出顺序不改变在盘字节）。该排序在每个 phrase-support 文本列的每行/每数组元素（`_add_value_tokens:187` ← `add_values:196` / `add_array_values:221`）上纯属浪费。验证器结论：排序确属冗余且安全可删，但量级被高估——真正更大的 per-row 成本是 `positioned` 向量本身的分配以及 `make_phrase_bigram_term` 每对的 std::string 堆分配；该优化为"近乎免费的清理"，非吞吐推动者。 + - 预期收益：build/compaction 路径每行省一次 O(M log M) 排序 + 一次向量分配（向量复用为成员后）。 + +- **B（F35）**

等价物的语义/调用约定与 SNII 用法错配，迁移需在每个 use-site 重写（如 R02 doris::Slice 可变语义 vs SNII 只读解码；R09 read_at 单点 vs read_batch 合并契约）。 +- **性能退化**：Doris 实现引入 SNII 热路径不可接受的开销（如 R04 解压每次走 std::mutex 上下文池，与 SNII const/无锁只读读端冲突）。 +- **字节语义不符**：SNII 解码依赖 `const uint8_t*` 无符号语义，Doris 用 `char*`（有符号、移位/比较易符号扩展 bug）。 +- **依赖重量**：复用会把 Doris 重头文件（profile / block_file_cache / S3 committer / pipeline exec 依赖）拽进本应轻量、CLucene-free、可独立测试的 SNII 核心。 +- **特例 reuse-with-extension**（R01）：Doris 实现最优，但需小幅扩展以保语义保真（如新增 `INVERTED_INDEX_SNII_*` ErrorCode 让 kNotFound 的「越界」语义 1:1 对齐，而非误映射到「文件未找到」）。 + +### Step 3 —

local_file.h:36），而本地后端实际只服务 spill 的大块写。Doris `appendv` 用 writev + page cache，等价或更好。 +- **字节语义无关**：spill 是进程内私有 scratch，回读顺序由 stream_into 保证（spillable_byte_buffer.h:99-117），任何保序的本地 writer 均可，故无

`DorisSniiFileReader` 适配器包一层，保持 `read_at(offset,len,vector*)` 调用形态不变。 +- 析构期 `std::remove(temp_path_.c_str())`（spillable_byte_buffer.h:48）保留不变（或改 `global_local_filesystem()->delete_file`）。 +- 删除

Doris's established inverted-index IO metrics (FileCacheStatistics::inverted_index_request_bytes/ read_bytes/range_read_count/serial_read_rounds, shared with CLucene fs_directory) already capture S3 read efficiency. Remove from io_common.h (FileCacheStatistics section arrays), cached_remote_file_reader (per-section populator + snii_section_type param of _update_stats), and block_file_cache_profile (reporter arrays, kSniiSectionNames, add_snii_section_counter, diff/init/update section loops); drop the now-dead test assertions. General file-cache metrics, the inverted_index_* II path, and is_index_data semantics are untouched. ninja doris_be green. --- be/src/io/cache/block_file_cache_profile.cpp | 105 ------------------ be/src/io/cache/block_file_cache_profile.h | 12 -- be/src/io/cache/cached_remote_file_reader.cpp | 24 +--- be/src/io/cache/cached_remote_file_reader.h | 2 +- be/src/io/io_common.h | 7 -- .../cache/cached_remote_file_reader_test.cpp | 3 - 6 files changed, 4 insertions(+), 149 deletions(-) diff --git a/be/src/io/cache/block_file_cache_profile.cpp b/be/src/io/cache/block_file_cache_profile.cpp index 3d65b6ea7c1f04..9953585262a457 100644 --- a/be/src/io/cache/block_file_cache_profile.cpp +++ b/be/src/io/cache/block_file_cache_profile.cpp @@ -26,22 +26,6 @@ namespace doris::io { -namespace { - -constexpr std::array kSniiSectionNames { - "Unknown", "Meta", "Dict", "Posting", "Bsbf", "Norms", "NullBitmap"};

META reads already set is_index_data=true at the source (index_file_reader) and non-meta reads default to false, so derive is_index_data by inheriting the scoped io_ctx instead of re-classifying. This removes the SNII section taxonomy from the general io_common.h and eliminates the per-read shared_lock. Behavior preserved (META->INDEX cache tier, non-meta->NORMAL). Drop the now-obsolete section-routing test and its helpers. ninja doris_be green. --- be/src/io/io_common.h | 10 --- be/src/storage/index/index_file_reader.cpp | 6 -- .../storage/index/snii/snii_doris_adapter.cpp | 78 +------------------ .../storage/index/snii/snii_doris_adapter.h | 18 ----- .../storage/index/snii_doris_adapter_test.cpp | 66 +--------------- 5 files changed, 5 insertions(+), 173 deletions(-) diff --git a/be/src/io/io_common.h b/be/src/io/io_common.h index c3addb2e133280..151d34a3a0351f 100644 --- a/be/src/io/io_common.h +++ b/be/src/io/io_common.h @@ -43,15 +43,6 @@ enum class ReaderType : uint8_t { namespace io { -enum SniiSectionType : uint8_t { - SNII_SECTION_UNKNOWN = 0, - SNII_SECTION_META = 1, - SNII_SECTION_DICT = 2, - SNII_SECTION_POSTING = 3, - SNII_SECTION_BSBF = 4, - SNII_SECTION_NORMS = 5, - SNII_SECTION_NULL_BITMAP = 6, - SNII_SECTION_COUNT = 7, enum class FileCacheMissPolicy : uint8_t { READ_THROUGH_AND_WRITE_BACK = 0, REMOTE_ONLY_ON_MISS = 1, @@ -199,7 +190,6 @@ struct IOContext { FileCacheStatistics* file_cache_stats = nullptr;

Route the PFOR/zstd decode buffers through it (prx_pod/frq_pod decode_pfor_runs assign(n,0) -> resize_uninitialized; zstd_decompress resize -> resize_uninitialized; drop the redundant pos_flat reserve in decode_pfor_payload_csr). Eliminates the warm-reuse memset; reader/writer-only, zero on-disk change, decode byte-identical. Verified: doris_be_test (ASAN) 432 SNII tests pass (incl. 5 new SniiUninitializedBuffer cases: byte-proof of no zero-fill, capacity stability, CSR + zstd warm-reuse no stale tail); existing 427 unchanged. --- be/src/snii/common/uninitialized_buffer.h | 82 ++++++++++ .../snii/core/src/encoding/zstd_codec.cpp | 5 +- .../index/snii/core/src/format/frq_pod.cpp | 4 +- .../index/snii/core/src/format/prx_pod.cpp | 8 +- .../snii/common/uninitialized_buffer_test.cpp | 154 ++++++++++++++++++ 5 files changed, 249 insertions(+), 4 deletions(-) create mode 100644 be/src/snii/common/uninitialized_buffer.h create mode 100644 be/test/storage/index/snii/common/uninitialized_buffer_test.cpp diff --git a/be/src/snii/common/uninitialized_buffer.h b/be/src/snii/common/uninitialized_buffer.h new file mode 100644 index 00000000000000..65582ec8324574 --- /dev/null +++ b/be/src/snii/common/uninitialized_buffer.h @@ -0,0 +1,82 @@ +// Licensed to the Apache Software Foundation (ASF) under one +// or more contributor license agreements.

bad patterns return Status::InvalidArgument via re2.ok() (no exceptions). RE2 (Google) dialect rejects backreferences/lookaround (now InvalidArgument) -- intentional, aligns with Doris legacy/query_v2 RE2. T02 (phrase): merge the per-tail PRX fetch() loop into one shared BatchRangeFetcher round (PRX read_batch rounds 3->1); result set byte-identical. T03 (adapter): parallelize DorisSniiFileReader::read_batch across sections (one serial round) + single-section direct read; per-seg private stats slots. T04 (dict cache): new request-scoped snii::reader::DictBlockCache + a dict_decode_counter() seam -- a multi-term query decodes each DICT block once. Delivered as an optional cache param (default nullptr = current behavior); wiring the production query operators to thread a per-query cache is a follow-up. Forward-declared in logical_index_reader.h to keep the cache header out of the ~500 transitive includers. T05 (writer): SPIMI vocab transparent-hash lookup + store each string once. All reader/writer-only: ZERO on-disk byte change, decode byte-identical, CRCs unchanged; reuses the T19 resize_uninitialized primitive. Verified: doris_be_test (ASAN) 476 SNII tests pass (0 failed), incl. ~44 new functional + deterministic-perf gates (RE2 golden equivalence, serial_rounds==1, dict_decode_counter==unique_blocks, vocab materialization==unique terms). --- be/src/snii/format/dict_block.h | 17 +- be/src/snii/query/internal/regex_prefix.h | 37 + be/src/snii/query/regexp_query.h | 6 +- be/src/snii/reader/dict_block_cache.h | 124 +++ be/src/snii/reader/logical_index_reader.h | 36 +- be/src/snii/writer/spimi_term_buffer.h | 72 +- .../index/snii/core/src/format/dict_block.cpp | 68 +- .../snii/core/src/query/phrase_query.cpp | 196 +++-- .../snii/core/src/query/regexp_query.cpp | 51 +- .../core/src/reader/logical_index_reader.cpp | 152 +++- .../core/src/writer/spimi_term_buffer.cpp | 165 +++- .../storage/index/snii/snii_doris_adapter.cpp | 193 ++++- .../storage/index/snii/snii_doris_adapter.h | 26 + .../storage/index/snii_doris_adapter_test.cpp | 296 ++++++- be/test/storage/index/snii_query_test.cpp | 795 +++++++++++++++++- .../storage/index/snii_spimi_intern_test.cpp | 325 +++++++ 16 files changed, 2359 insertions(+), 200 deletions(-) create mode 100644 be/src/snii/query/internal/regex_prefix.h create mode 100644 be/src/snii/reader/dict_block_cache.h create mode 100644 be/test/storage/index/snii_spimi_intern_test.cpp diff --git a/be/src/snii/format/dict_block.h b/be/src/snii/format/dict_block.h index ce8cd91316a789..c8b24f29208251 100644 --- a/be/src/snii/format/dict_block.h +++ b/be/src/snii/format/dict_block.h @@ -63,7 +63,7 @@ inline constexpr uint8_t kDictBlockFormatVer = 2; // block_flags bit definitions. namespace dict_block_flags { -inline constexpr uint8_t kHasPositions = 1u << 0; // whether to write prx_base / .prx fields +inline constexpr uint8_t kHasPositions = 1U << 0; // whether to write prx_base / .prx fields // bit1-7 reserved } // namespace dict_block_flags @@ -160,3 +160,18 @@ class DictBlockReader { }; } // namespace snii::format + +// Test-only instrumentation seam. dict_decode_counter() returns a process-global +// count of DICT block decodes performed by DictBlockReader::open -- i.e. the +// optional zstd decompress + CRC verify + anchor parse that turns on-disk block +// bytes into a usable reader.

Includes are now full-path "storage/index/snii/...". Namespace: the core is now doris::snii (was bare top-level snii); the Doris integration layer stays doris::segment_v2::snii_doris. Redundant doris::snii:: / doris::Status / doris::ErrorCode qualifiers dropped inside the doris::snii/doris namespaces; Doris-global refs that the new nesting would otherwise mis-resolve are global-qualified (::doris::io / ::doris::Slice / ::doris::segment_v2). temp_dir: resolve_temp_dir() now uses ExecEnv::get_tmp_file_dirs()->get_tmp_file_dir() (same source as index_file_writer.cpp) under a dedicated "snii" subdirectory, instead of the env-var fallback. Unit tests initialize tmp_file_dirs via a global gtest environment (be/test/storage/index/snii/snii_test_env.cpp). Also: CLucene-decoupling guard updated to the new core path (scans only core-module .h/.cpp; integration + docs excluded); Chinese code comments / assert messages converted to English (kept the intentional CJK UTF-8 test-data string). Storage CMake unchanged (recursive glob). Verified: doris_be_test (ASAN) 474 SNII tests pass, 0 failed. --- .../snii/query/internal/docid_conjunction.h | 102 ---- be/src/storage/index/index_file_reader.cpp | 20 +-

the cold S3 over-fetch is a file-cache coarse-block effect, NOT a batching gap. Delivered the byte-identical wins: streaming docid-union into dedup-capable sinks (DocIdSink::dedups) + union_sorted_many reserve-by-total (capped), and threaded the request-scoped DictBlockCache through the OR resolve path (dedups same-block dict reads/zstd). T07: DICT entry key-first decode (decode_dict_entry split into key/rest/skip; find_term + visit_prefix_range skip non-matching bodies). Decode byte-identical. T08: wildcard matcher reuses scratch (internal::WildcardMatcher) -> removes 2 heap allocs per visited dictionary term. T10: select_covering_windows as a monotonic two-pointer cursor (O(C+N)).

Problem Summary: Under a cold cache, Doris parallel scanners `_lazy_init` the same segment concurrently. Each independently misses the inverted-index searcher/query caches before the leader populates them, and redundantly opens + decodes that segment's SNII index (the ~185KB per-index meta plus the term postings). When index opens are slow (true-cold remote storage) this doubles the per-segment index reads and decode work. This adds a request-spanning single-flight: concurrent identical queries (same segment file + column + query type + terms) in `SniiIndexReader::query` collapse to a single execution. The leader computes the result bitmap while followers await and reuse it, eliminating the duplicate open/decode. The single-flight is a generic, future-based helper (`be/src/storage/index/snii/common/single_flight.h`) that performs no IO under its lock, preserving the SNII no-IO-under-lock rule, and it is a no-op when opens are fast (the searcher cache already dedups). Query body size is kept in check by extracting the open+execute step into `_compute_query_bitmap`. Verified on cloud_sim with a slow-open simulation: per-query SNII reads dropped from 3958 to 1990 and searcher-cache opens from ~414 to 208 (one per segment); identical work and latency when opens are fast. ### Release note None ### Check List (For Author) - Test: Unit Test / Manual test - Unit Test: ./run-be-ut.sh --run --filter='SniiSingleFlight.*' -j "$(nproc)" - Manual test: ./build.sh --be; redeployed BE to cloud_sim; ran SNII cold OR (MATCH_ANY) and confirmed correct count with reduced duplicate opens - Behavior changed: No --- .../storage/index/snii/common/single_flight.h | 100 ++++++++++++++ .../storage/index/snii/snii_index_reader.cpp | 72 +++++++++- be/src/storage/index/snii/snii_index_reader.h | 9 ++ .../index/snii/common/single_flight_test.cpp | 127 ++++++++++++++++++ 4 files changed, 305 insertions(+), 3 deletions(-) create mode 100644 be/src/storage/index/snii/common/single_flight.h create mode 100644 be/test/storage/index/snii/common/single_flight_test.cpp diff --git a/be/src/storage/index/snii/common/single_flight.h b/be/src/storage/index/snii/common/single_flight.h new file mode 100644 index 00000000000000..f3cdbaa9547b14 --- /dev/null +++ b/be/src/storage/index/snii/common/single_flight.h @@ -0,0 +1,100 @@ +// Licensed to the Apache Software Foundation (ASF) under one +// or more contributor license agreements.

Problem Summary: For a real text column the per-segment SNII block-split bloom (BSBF) is sized to the vocabulary -- median ~12MB/segment (up to 64MB), essentially always over the 256KB resident threshold, so it is never resident. Each term lookup then issued a 32B bloom-block probe at a hash-scattered offset (plus a 28B header read at open) -- hundreds of tiny, isolated reads per query (~618 reads / <20KB for a 2-term OR over 208 segments). At the file-cache 1MiB block granularity each isolated probe drags a full block, and on cold remote storage each is a separate round-trip: pure read amplification that the v3 CLucene format (which has no BSBF) does not pay. This gates the bloom on residency. It is read and used only when the whole filter fits under the resident cap (in-memory probes, no extra IO); a non-resident bloom is skipped entirely -- no header read at open, no per-term probe -- and every term falls through to the existing sti -> dict lookup, which returns the true found/absent. Skipping a false-positive-only bloom cannot change results, and at 1MiB block granularity a non-resident probe never saved a physical block anyway (an absent term costs one dict block either way). Reader-only: no on-disk format change, no reimport. Verified on cloud_sim, true cold (BE restart + file-cache clear per query), 10B-row otel logs, identical results: - OR cold 3921->1077ms (-72%), physical 1.12GB->909MB; PHRASE 4053->1655ms (-59%); PPREFIX 4869->3640ms (-25%); AND 1015->963ms (-5%). - post-fix SNII now beats v3/CLucene on every query (OR 1077 vs 3374ms, PHRASE 1655 vs 6289ms), reading less physical and 1.5-4x less logical. ### Release note None ### Check List (For Author) - Test: Unit Test / Manual test - Unit Test: ./run-be-ut.sh --run --filter='SniiSegmentReaderTest.NonResidentBsbfIsSkippedNotProbed:SniiCompoundWriter.MultiSuperBlockReadBack' -j "$(nproc)" - Manual test: ./build.sh --be; redeployed to cloud_sim; true-cold A/B (BE restart + file-cache clear per query) over otel10b_snii / otel10b_phrase40_snii vs otel10b_v3 - Behavior changed: No (results identical; a non-resident bloom is simply no longer consulted) --- .../snii/reader/logical_index_reader.cpp | 59 ++++++------ .../snii/writer/snii_compound_writer_test.cpp | 91 ++++++++++++++++--- be/test/storage/index/snii_query_test.cpp | 37 ++++---- 3 files changed, 128 insertions(+), 59 deletions(-) diff --git a/be/src/storage/index/snii/reader/logical_index_reader.cpp b/be/src/storage/index/snii/reader/logical_index_reader.cpp index 2879417459b79a..90e98f2479f1a4 100644 --- a/be/src/storage/index/snii/reader/logical_index_reader.cpp +++ b/be/src/storage/index/snii/reader/logical_index_reader.cpp @@ -33,7 +33,6 @@ namespace doris::snii::reader { using format::BlockRef; using format::bsbf_hash; -using format::bsbf_probe; using format::DictBlockDirectoryReader; using format::DictBlockReader; using format::DictEntry; @@ -289,24 +288,31 @@ Status LogicalIndexReader::open(io::FileReader* file_reader, IndexTier tier, boo DictBlockDirectoryReader::open(out->meta_.dict_block_directory_bytes(), &out->dbd_)); RETURN_IF_ERROR(out->load_resident_dict_blocks()); - // Block-split bloom XFilter.

Problem Summary: SniiSegmentReader::open read the 21-byte bootstrap header at offset 0 of every segment .idx, but the decoded value was never used and the container format_version is already validated -- more strictly, by exact-match -- by the tail pointer that open reads anyway. On a cold query that offset-0 read is one isolated 1MiB file-cache block and one remote round-trip per segment, pure read amplification. This removes the bootstrap read from the open path (and the now-unused ReadBootstrap helper / include). The container version stays gated by ReadTailPointer (TAIL magic + format_version exact-match + tail crc) and the meta_format_version checks; the bootstrap header is still written on disk and still covered by its own format unit tests, so the on-disk format and inspect tooling are unchanged. Reader-only, no format change, no reimport. The bootstrap's min_reader_version forward-compat gate is intentionally retired with the read (documented inline): future format evolution must bump format_version, which the tail rejects. Verified true-cold (BE restart + file-cache clear per query), identical results: OR cold 1723->872ms, 909->701MB physical (-208MB = the ~208 offset-0 blocks). ### Release note None ### Check List (For Author) - Test: Unit Test (SniiSegmentReaderOpen.*) - Behavior changed: No (results identical; version still gated by the tail) --- .../index/snii/reader/snii_segment_reader.cpp | 25 +- .../index/snii/reader/snii_segment_reader.h | 17 +- .../reader/snii_segment_reader_open_test.cpp | 228 ++++++++++++++++++ 3 files changed, 253 insertions(+), 17 deletions(-) create mode 100644 be/test/storage/index/snii/reader/snii_segment_reader_open_test.cpp diff --git a/be/src/storage/index/snii/reader/snii_segment_reader.cpp b/be/src/storage/index/snii/reader/snii_segment_reader.cpp index 17878e451765ee..5d7d4486012822 100644 --- a/be/src/storage/index/snii/reader/snii_segment_reader.cpp +++ b/be/src/storage/index/snii/reader/snii_segment_reader.cpp @@ -21,7 +21,6 @@ #include #include "storage/index/snii/encoding/crc32c.h" -#include "storage/index/snii/format/bootstrap_header.h" #include "storage/index/snii/format/format_constants.h" #include "storage/index/snii/format/per_index_meta.h" #include "storage/index/snii/format/stats_block.h" @@ -29,7 +28,6 @@ namespace doris::snii::reader { -using format::BootstrapHeader; using format::IndexTier; using format::PerIndexMetaReader; using format::StatsBlock; @@ -38,13 +36,6 @@ using format::TailPointer; namespace { -// Reads the bootstrap header from the front of the file and validates it. -Status ReadBootstrap(io::FileReader* reader, BootstrapHeader* bh) { - std::vector buf; - RETURN_IF_ERROR(reader->read_at(0, format::kBootstrapHeaderSize, &buf)); - return format::decode_bootstrap_header(Slice(buf), bh); -} - // Reads the fixed tail pointer (last tail_pointer_size() bytes) of the file.

-1,132 +0,0 @@ -# SNII 倒排索引性能与并发改进 — 总体设计文档 - -## 1. 背景与目标 - -### 1.1 背景 -SNII 是 Apache Doris BE 的追加写复合倒排索引容器（magic `"SNII"`，`kFormatVersion=2`，见 `be/src/storage/index/snii/format/format_constants.h:14-16`）。一个容器内含多个 logical index，每个由交错的 posting region + DICT block region + per-index meta 组成。词查找链路为 BSBF bloom → SampledTermIndex → DICT block directory → 常驻/按需 DICT block → `DictBlockReader::find_term` → `DictEntry`。读路径经 `FileReader` 抽象（`be/src/storage/index/snii/io/file_reader.h`）统一收口，本地文件与 S3 可互换；`BatchRangeFetcher`（`be/src/storage/index/snii/io/batch_range_fetcher.h`）合并远程区间，生产路径由 `DorisSniiFileReader`（`be/src/storage/index/snii/snii_doris_adapter.cpp`）包装 Doris IO 栈。 - -本工作把一轮多智能体性能 review（48 条确认 finding，去重为 25 个任务、分 5 个批次）加一项并发/锁专项（T26）产品化。已接入 Doris 查询执行的算子面为：docid 过滤（term/match/any/all）、phrase、phrase-prefix、prefix、wildcard、regexp。 - -### 1.2 目标（Goals） -- 降低**已接入路径**（phrase/IO）的远程读放大：PRX 单轮批量读（T02）、adapter `read_batch` 并行去重排（T03）、DICT block 解压结果缓存（T04）。 -- 降低查询 CPU：regexp 用 RE2（T01）、≥3 词短语用 bigram 候选（T06）、key-first DICT 解码原语（T07）、wildcard 双指针（T08）等。 -- 降低构建吞吐/峰值内存：SPIMI 词表单份存储（T05）、PFOR `choose_width` 直方图（T11）、freqs 单遍统计（T12）等。 -- 消除解码路径微浪费：统一未初始化 resize 原语（T19）等。 -- **并发安全**：保证不引入"锁内 IO"或"粗锁串行化并发查询"的回归（T26、约束 T04/T07）。 -- 一处格式层优化（T18）在 launch 前完成。 - -### 1.3 非目标（Non-Goals） -- **不改变在盘格式**——除 T18 外，全部 25 个任务都是 reader/writer-only，前后兼容。 -- **不做 BM25 打分路径优化**：scoring 模块（`scoring_query_*`、WAND，`be/src/storage/index/snii/query/scoring_query.h`/`bm25_scorer.h`）尚未接入 Doris 查询执行，相关 finding F04/F24/F45 全部 DEFER（见 §7）。 -- 不引入新的第三方依赖（RE2、Google Benchmark、libzstd 均已在 thirdparty）。 -- 不改变查询语义/结果集——所有改动须保持结果位级一致。 - -## 2. 任务分类与批次 - -| 批次 | 主题 | 任务 | -|---|---|---| -| Batch 1 | 远程读放大 + 并发 + RE2 | T01 RE2、T02 PRX 单轮批量、T03 adapter `read_batch` 并行、T04 DICT 解压缓存、T05 SPIMI

per-task plan 复用） - -### 3.1 (a) 未初始化/默认初始化 resize 原语（T19） -**问题**：解码缓冲普遍走 `out->resize(n)`（值初始化清零）随后被全量覆写——`be/src/storage/index/snii/encoding/zstd_codec.cpp:21`（`resize(expected_uncomp_len)` 后 `ZSTD_decompress` 全量写）、PFOR 解码缓冲、CSR offsets 等。清零是纯浪费。 - -**设计**：新增唯一头文件 `be/src/storage/index/snii/common/uninitialized_buffer.h`，提供： -``` -namespace doris::snii { template void resize_uninitialized(std::vector& v, size_t n); } -``` -对 trivially-copyable `T`，扩张部分**不做值初始化**；可用 default-init allocator 包装（`std::vector>` 的 typedef `RawBuffer`）或在受控处用 `resize` + 显式语义注释。**约束**：仅用于"resize 后立即被解码全量覆写"的缓冲；任何读取未写区间的路径禁止使用。所有现有 `resize`-then-overwrite 点（T19 列举：zstd/pfor/CSR/window framing）统一切换到该原语。**验证**：bit-identical 输出 + realloc/清零计数（见 3.5）。 - -### 3.2 (b) RE2 集成与 CMake 链接（T01） -**现状**：`regexp_query.cpp:3` 用 ``，`:77-87` 用 `std::regex`/`std::regex_match`（**全仓唯一** std::regex 使用点）。RE2 **已是 thirdparty target**：`be/cmake/thirdparty.cmake:57` `add_thirdparty(re2)` 已把 `re2` 追加进 `COMMON_THIRDPARTY` → `DORIS_DEPENDENCIES` → `DORIS_LINK_LIBS`（`be/CMakeLists.txt:589-609`），`libre2.a` 在 `thirdparty/installed/lib`，版本 `re2-2021-02-02`。 - -**设计**：T01 只需在 `regexp_query.cpp` 改用 `#include `、以 `RE2` 对象 + `RE2::FullMatch`（整词匹配语义，对齐现 `regex_match`）替换；编译期一次性构造、对 term 流式匹配。**CMake 通常无需新增**——`Storage` 经 `DORIS_LINK_LIBS` 传递链接 re2；若链接缺符号，则在 `be/src/storage/CMakeLists.txt:41-42` 给 `Storage` 显式 `target_link_libraries(Storage PRIVATE re2)`。须保留非法 pattern 的 `Status::InvalidArgument` 错误路径（RE2 用 `re2.ok()` 判定，不抛异常）。**验证**：非法 pattern 返回错误；与旧 std::regex 在一组黄金 pattern/term 上结果集逐字节一致；隐藏 bigram term 不外泄（已有用例 `snii_query_test.cpp:523-533`）。 - -### 3.3 (c) DICT-block 解压缓存设计与并发模型（T04，被 T07 复用） -**问题**：on-demand DICT block 解码到栈局部 `OnDemandDictBlock`（`be/src/storage/index/snii/reader/logical_index_reader.h:124-130`；实现 `logical_index_reader.cpp` 的 `dict_block_reader_for_ordinal:143-159` → `open_dict_block` → `zstd_decompress`，约 64KB/块）。同一查询多词命中同一块时反复解压（F08/F20）。 - -**关键约束**：`LogicalIndexReader` 经 `InvertedIndexSearcherCache` **跨并发查询共享**（`snii_index_reader.cpp` `_get_logical_reader`），给它加可变缓存即引入共享可变状态。CONCURRENCY.md 隐患 1 明确：朴素实现（一把锁包住整张缓存且锁内做 ~64KB zstd 解压 + CRC）会同时犯"锁粒度过粗"+"锁内重活"，串行化最热的 term lookup。 - -**设计（两方案，红线统一）**： -- **方案 A（默认推荐）request-scoped（每查询）块缓存**：缓存随查询生命周期（挂在 per-query 上下文，如一个 `DictBlockCache*` 经 lookup/prefix 路径透传），**无共享可变状态、完全无锁**。解决"同查询多词反复解压"主因；跨查询复用交给 Doris page/file cache（字节级）+ searcher cache（小词典常驻）。 -- **方案 B（备选）分片 / lock-striped 缓存 + 锁外解压**：N 个 shard 按 block ordinal 哈希；shard 锁仅保护 map 查/插；**解压在锁外的局部缓冲完成后再插入**；并发 miss 容忍偶发重复解压（可选 single-flight 合并）。读者持 `shared_ptr` 在使用期无锁存活。 -- **红线（硬约束，写入 §4）**：**任何情况下不得在持任何锁期间执行 zstd 解压、CRC 或 `FileReader` IO。** - -T04 默认实现方案 A；方案 B 仅当确证需要跨查询块复用时启用，并须独立基准 + 通过 §4 全部并发不变量测试。**T07（key-first 解码原语）消费缓存**：解码后的 DICT block 暴露 key-first `find_term`（精确）+ 前缀流式 early-stop 扫描；块来自缓存还是新解码对 T07 透明。 - -### 3.4 (d) MOCK/COUNTING FileReader 测试骨架（T02/T03/T04/T26） -仓内**已有三套可复用骨架**，per-task plan 必须基于它们做确定性断言，禁止新造： -- **`MemoryFile`**（`be/test/storage/index/snii_query_test.cpp:53-101`）：同时实现 `doris::snii::io::FileReader`+`FileWriter`，记录 `reads()`（每次 offset/len）、`read_bytes()`、`clear_reads()`。用于 snii 层 round-trip / 精确区间断言（已被 `:301-317`/`:471-483`/`:556-568` 等大量使用）。配套夹具 `build_reader()`（`:203-275`，9000 文档、`kDocsPositions`、含可选 phrase bigram）是 reader 侧标准 fixture。 -- **`RecordingFileReader`**（`be/test/storage/index/snii_doris_adapter_test.cpp:53-97`）：实现 Doris `io::FileReader::read_at_impl`，捕获 `CapturedRead{offset,len,io_ctx}`（含 IOContext 旗标 + `file_cache_stats`）。用于断言合并（`read_batch` → 1 次物理读，`:158-160`）与 IOContext 透传。 -- **`MeteredFileReader`**（`be/src/storage/index/snii/io/metered_file_reader.h`）：模拟 1MiB-block FileCache，`metrics()` 返回 `IoMetrics{read_at_calls, serial_rounds, range_gets, remote_bytes, total_request_bytes}`，`reset_metrics()` 模拟冷缓存；`read_batch` 至多 1 个 serial round。是 serial-round / range-GET 的"标尺"。 - -**新增（本设计统一约定）**：在共享缓存/解压计数上引入一个 test seam——进程级原子计数器 `doris::snii::testing::dict_decode_counter()`（在 `open_dict_block`/dict-block zstd 解码处自增，测试间可 reset）。它给 T04/T26 提供**确定性 decompress-count** 断言；FileReader 的 read-count 作旁证（非常驻块每解码对应一次 DICT 区读）。并发不变量验证（"解压锁外执行"）通过在解码入口断言"本缓存锁未被本线程持有"实现（计数=0）。 - -### 3.5 (e) 微基准 / 分配计数 / 位级黄金输出约定 -- **微基准（report-only，非 CI 门禁）**：复用 `be/benchmark` Google Benchmark 骨架——新增 `be/benchmark/benchmark_snii_*.hpp` 并在 `benchmark_main.cpp` `#include`。仅在 `-DBUILD_BENCHMARK=ON` 且 `CMAKE_BUILD_TYPE=RELEASE` 时编译为 `benchmark_test`（`be/CMakeLists.txt:1030-1038`，非 RELEASE 直接 `FATAL_ERROR`），默认关闭——故**绝不进 CI 门禁**。`QueryProfileScope`（`be/src/storage/index/snii/query/query_profile.h`）提供 `elapsed_ns` + IO delta 供测内计时回退。 -- **分配/realloc 计数**：优先用 `vector::capacity()` 稳定性断言（reserve 一次、后续无 realloc → capacity 不变）；需要精确次数时用小型 `CountingAllocator` 注入受测缓冲。禁止全局 `new`/`delete` override。 -- **位级黄金输出**：纯重构/解码微优化任务（T13/T14/T19/T21/T22）的金标准是——捕获改前路径（或冻结 golden）输出字节，改后断言 `ByteSink::buffer()`/解码结果**逐字节相等**（仓内已普遍用解码相等模式，如 `snii_query_test.cpp:662-704`）。 - -## 4. 并发与锁设计原则（规范性，源自 CONCURRENCY.md） - -**现状（已读码确认，无需"修旧坑"）**：当前**没有锁内 IO，也没有粗锁串行化查询**。 -- `DorisSniiFileReader::_section_ranges_mutex`（`shared_mutex`，`snii_doris_adapter.h:98`）：`_classify_section`（`snii_doris_adapter.cpp:134-155`）持 `shared_lock` 仅内存扫描 ≤5 个 range，**返回即释放，IO 在锁外**（`read_at:166-180`、`read_batch:209-283` 均 classify→释放→`_read_at`）。`register_section_refs`（`:108-132`）持 `unique_lock` 仅 push ≤5 range，冷路径。非并发瓶颈。 -- `g_api_mu`（`s3_object_store.cpp:29`）：在 `#ifdef SNII_WITH_S3` 内、且该文件已被 `Storage` 构建排除（`be/src/storage/CMakeLists.txt:31`），仅护 `Aws::InitAPI` 引用计数，**非生产路径**。 -- 共享 `LogicalIndexReader` 读路径 const 无锁；on-demand 块解码到栈局部。安全。 - -**规范红线（所有任务必须遵守，重点约束 T04/T07/任何新增 per-reader 状态）**： -1. **NO-IO-UNDER-LOCK**：任何锁的临界区内禁止 `FileReader` IO、zstd 解压、CRC 等重活。把"分类（持锁）"与"IO（无锁）"在**代码结构上拆为独立函数**，便于单测断言。 -2. **共享 reader 缓存必须 request-scoped，或分片且解压在锁外**（§3.3 红线）。 -3. **reader-open miss 单飞（single-flight）**（隐患 2）：`_get_logical_reader` 在 cache miss 时直接 `open_snii_index`（meta+resident dict+BSBF 的 IO）再 insert，**无 in-flight 去重** → N 个并发 miss 同 index ⇒ N 次打开 IO。设计：对 `searcher_cache_key` 加 per-key in-flight map（`std::mutex` 仅护小 map + `std::shared_future`/`condition_variable`），首个 miss 占位后**在 in-flight 锁外执行打开 IO**，其余等待复用。**等待用条件变量/future，绝不持打开锁做 IO**。 - - **待确认项**：`InvertedIndexSearcherCache` 基于 Doris `LRUCachePolicy`（分片 LRU，`be/src/storage/index/inverted/inverted_index_cache.h:48-136`）——lookup/insert 各自线程安全，但 lookup→insert 之间非原子，**只去重 insert、不去重 open IO**。故 SNII 侧 single-flight 仍必要；T26 须先确证此语义再定实现。 - -**单体可验证（确定性，CI 可门禁）**： -- 锁内禁 IO 不变量：断言 IO 函数不接触 `_section_ranges_mutex`（结构分离 + mock read 回调探针）。 -- T04 缓存并发：N 线程并发 lookup → 断言（a）`dict_decode_counter()` == 唯一块数（方案 A）或 ≤ 唯一块数×分片冗余上界（方案 B）；（b）解码入口"缓存锁未持有"计数=0；（c）TSAN 干净。 -- single-flight：N 并发 miss 同 key → mock/计数 reader 断言底层 `open`/meta 读次数 == 1。 -- 吞吐：固定并发度 lookup QPS 改前后对比（report-only）。 - -## 5. 格式兼容策略 - -- **唯一格式变更：T18**（F11，prelude 窗口行裁剪可推导冗余字段）。其余 25 任务 reader/writer-only，零在盘变更，天然前后兼容，可任意顺序落地。 -- **当前版本锚点**：`kFormatVersion=2`、`kMetaFormatVersion=1`（`format_constants.h:16,24`）。`format_constants.h:18-23` 明确："pre-launch 只有一种 meta 布局 = v1，仅在 **launch 之后**、需与已写索引共存时才 bump；pre-launch 变更直接折叠进 v1"。 -- **T18 策略（pre-launch 优先）**：SNII 尚未 launch（无 `lifecycle: launched` 模块），T18 应**在 launch 前尽早落地**，直接折叠进 v1，**无需 bump、无需兼容 shim**——这是最省且符合设计意图的路径。 -- **兜底门控**：若 T18 有滑出 launch 窗口的风险，则**必须**二选一门控：(a) 新增 `frq_prelude` flag bit（`be/src/storage/index/snii/format/frq_prelude.h:70-73` `frq_prelude_flags`）标记"trimmed prelude"，reader 双路兼容；或 (b) bump `kMetaFormatVersion` 到 2 并让 reader 同时处理 v1/v2。亦可走 `SectionType::kFeatureBits=9`（`format_constants.h:37`）作 feature 协商。 -- **铁律**：任何写 v1 之外字节的改动，未经上述门控不得合入。 - -## 6. 测试与验证基线 -所有任务遵循 TDD（RED→GREEN→REFACTOR），每个 plan 必含 `功能验证` 与 `性能验证（单体）` 两节（详见 conventions）。功能用例进 `be/test/storage/index/snii_*_test.cpp`（GLOB 自动纳入 `doris_be_test`，无需改 CMake）。性能优先确定性断言（fetch/open/decompress 计数、realloc 计数、位级一致、操作计数），wall-clock 仅 report-only。 - -## 7.

-## 4. `性能验证（单体）`（强制）— 确定性优先 -**首选确定性断言（可进 CI 门禁），按相关性选用：** -- **fetch/round 计数**：`MeteredFileReader::metrics()` 的 `serial_rounds`/`range_gets`（`be/src/storage/index/snii/io/metered_file_reader.h`）；或 `MemoryFile::reads().size()`。例：T02 断言一次 phrase 查询 `serial_rounds == 1`。 -- **物理读合并计数**：`RecordingFileReader::reads()`（断言合并后物理读次数与 offset/len，如 `snii_doris_adapter_test.cpp:158-160`）。 -- **open 计数（single-flight）**：N 并发 miss 同 key → 底层 `open`/meta 读次数 == 1。 -- **decompress 计数**：`doris::snii::testing::dict_decode_counter()`（测试间 reset）断言解压次数 == 唯一块数。 -- **realloc/alloc 计数**：优先 `vector::capacity()` 稳定性（reserve 一次后 capacity 不变）；需精确次数用 `CountingAllocator`。禁止全局 `new` override。 -- **操作计数**：在热点放可计数 seam（如 `choose_width` 比较次数）断言复杂度下降。 -- **位级黄金输出**：纯重构/解码任务断言 `ByteSink::buffer()`/解码结果改前后逐字节相等。 -- **IoMetrics delta**：`IoMetrics`（`io_metrics.h`）+ `delta()` 断言 `read_at_calls`/`remote_bytes` 不增。 - -**wall-clock 计时仅 report-only，永不作 CI 门禁。** 微基准用 `be/benchmark` Google Benchmark 骨架（新增 `benchmark_snii_*.hpp` + `#include` 进 `benchmark_main.cpp`），仅 `-DBUILD_BENCHMARK=ON` 且 RELEASE 编译，默认关闭。测内计时回退用 `QueryProfileScope`（`query_profile.h`）。 - -## 5. 并发与锁规则（任何触及共享 reader 状态的任务强制） -- **NO-IO-UNDER-LOCK（红线）**：任何锁临界区内禁止 `FileReader` IO / zstd 解压 / CRC。把"分类（持锁）"与"IO（无锁）"拆成独立函数。 -- **共享 reader 缓存**：必须 **request-scoped（每查询、无共享可变状态、无锁）**，或 **分片且解压在锁外**（shard 锁仅护 map 查/插，解压在锁外局部缓冲完成后插入）。默认 request-scoped。 -- **reader-open miss 单飞**：cache miss 打开须 single-flight（per-key in-flight map，`mutex` 仅护小 map，打开 IO 在锁外，等待用 future/cv）。 -- **共享 `LogicalIndexReader` 现为 const 无锁只读**；任何新增 per-reader 可变状态都受本节约束。 -- **并发测试强制项**（触及共享状态时）： - - TSAN 干净：`BUILD_TYPE_UT=TSAN ./run-be-ut.sh --run --filter='Snii*Concurrency*'`。 - - decompress-count == 唯一块数（确定性）。 - - "解压/IO 锁外执行"不变量：解码入口断言相关锁未被本线程持有（计数=0）。 - - single-flight：open-count == 1。 -- 不涉及共享状态的任务，在 `并发与锁影响` 节显式声明 "N/A，无共享可变状态"。 - -## 6. 验收标准格式 -每条验收标准写成可勾选、可机验的断言，三类齐备： -- `[功能]` 例：`phrase_query({"failed","order"})` 返回 `{5000,7000,8000}`（`EXPECT_EQ`）。 -- `[性能-确定性]` 例：单次 3-tail phrase-prefix 的 `serial_rounds == 1`（改前为 N）；或 `dict_decode_counter() == unique_blocks`；或编码字节改前后位级相等。 -- `[并发]`（如适用）例：8 线程并发 lookup 下 TSAN 无告警且 `dict_decode_counter() == unique_blocks`。 -每条标注验证手段（哪个 mock/counter/命令）。 - -## 7. 测试命名 -- 功能：`TEST(SniiTest, )`，沿用既有套件名（`SniiPhraseQueryTest`/`SniiSegmentReaderTest`/`SniiPrxPodTest`/`SniiTermQueryTest`/`DorisSniiFileReaderTest`）。 -- 确定性性能：`TEST(SniiTest, Issues)`，如 `PhraseQueryIssuesSingleBatchRound`、`PrefixExpansionDecodesEachBlockOnce`。 -- 并发：`TEST(SniiConcurrencyTest, )`，如 `ConcurrentLookupDecompressesEachBlockOnce`、`ConcurrentOpenMissIsSingleFlight`。 -- 位级重构：`...ProducesByteIdenticalOutput`。 - -## 8. 编码与格式 -- C++ 注释/标识符英文；遵循 `.clang-format`（提交前 `be-code-style`）。 -- 解码缓冲 resize-then-overwrite 一律改用 `doris::snii::resize_uninitialized`（T19 原语，`snii/common/uninitialized_buffer.h`）；仅限立即被全量覆写的缓冲。 -- regexp 用 `RE2`（``，已 thirdparty 链接），非法 pattern 经 `re2.ok()` 返回 `Status::InvalidArgument`，不抛异常。 -- 除 T18 外禁止改在盘字节；T18 须 pre-launch 折叠进 v1，或经 `frq_prelude` flag bit / bump `kMetaFormatVersion` 门控。 - -## 9. 构建/运行命令（速查） -- 单测：`./run-be-ut.sh --run --filter='SniiPhraseQueryTest.*'`（`--clean` 清理，`--coverage` 覆盖率，`--gdb` 调试）。 -- 并发测：`BUILD_TYPE_UT=TSAN ./run-be-ut.sh --run --filter='Snii*Concurrency*'`。 -- 微基准（非门禁）：`-DBUILD_BENCHMARK=ON` + RELEASE 构建 `benchmark_test`。 diff --git a/be/src/storage/index/snii/docs/perf/02-test-harness.md b/be/src/storage/index/snii/docs/perf/02-test-harness.md deleted file mode 100644 index 88d2ee3d24974a..00000000000000 --- a/be/src/storage/index/snii/docs/perf/02-test-harness.md +++ /dev/null @@ -1,47 +0,0 @@ -## 测试/基准 Harness 实测事实（供各 plan 引用真实基建） -

-### 设计红线（必须写入总设计文档，硬约束 T04 / T07 / 任何新增 per-reader 缓存） -- 方案 A（推荐之一）：**request-scoped（每查询）块缓存** —— 彻底消除共享可变状态、无锁；解决“同一查询多词命中同一 block 反复解压”这一主因；跨查询复用交给 Doris page/file cache + searcher cache。 -- 方案 B：**分片 / lock-striped 缓存 + 锁外解压** —— 锁只保护 map 的查/插；解压在锁外的局部缓冲完成后再插入；并发 miss 容忍偶发重复解压（可选 single-flight 合并）。 -- **红线：任何情况下不得在持锁期间执行 zstd 解压、CRC 或 FileReader IO。** - -## 三、隐患 2（现存）：冷启动 / 缓存淘汰时 reader 重复打开（thundering herd） - -`_get_logical_reader`（snii_index_reader.cpp:329-346）在 cache miss 时直接 `open_snii_index`（:334，执行 meta + resident dict + BSBF 的 IO）然后 insert，**无 in-flight 去重（single-flight）**。N 个并发 miss 同一 index ⇒ N 次打开 IO，N-1 次 insert 浪费。高 QPS + 冷缓存 / 淘汰风暴时拖并发。 - -### 修复方向 -- 对 `searcher_cache_key` 做 single-flight：per-key in-flight map（`mutex` + `condition_variable`/`shared_future`），首个 miss 打开、其余等待复用。**注意：single-flight 的等待用条件变量，绝不在持有打开锁时做 IO 之外的阻塞；打开 IO 本身在 in-flight 占位之后、全局锁之外执行。** -- 或先确认 `InvertedIndexSearcherCache::lookup/insert`（Doris 侧）的并发语义：是否分片锁、是否对并发同 key 的 insert/open 去重。若仅去重 insert 而 open 仍各自发生，则仍需 SNII 侧 in-flight 合并。 - -## 四、待确认项 -- `InvertedIndexSearcherCache`（storage/index/inverted/inverted_index_cache.h）的 lookup/insert 并发语义（分片锁？同 key 并发 insert 去重？）——决定隐患 2 是否需要 SNII 侧 single-flight。 - -## 五、单体可验证的并发测试要点（供 T26 / T04 复用） -1. **“锁内禁 IO”结构性不变量**：将“分类（持锁）”与“IO（无锁）”在代码结构上分离为独立函数；单测断言 IO 函数不接触 `_section_ranges_mutex`。或在 mock FileReader 的 read 回调中通过探针断言 `_section_ranges_mutex` 未被本对象持有。 -2. **T04 缓存并发（确定性）**：N 线程并发 lookup —— 断言（a）解压次数 == 唯一 block 数（request-scoped）或 ≤ 唯一 block 数 ×(分片冗余上界)（分片方案）；（b）在解压函数入口断言“本缓存锁未被持有”（锁外解压不变量，计数器=0）；（c）TSAN 无数据竞争。 -3. **single-flight（确定性）**：N 并发 miss 同 key —— 用 mock/计数 FileReader 断言底层 `open`/meta 读次数 == 1。 -4. 吞吐（report-only，非 CI 门禁）：固定并发度下的 lookup QPS，对比加缓存前后，确认无并发回归。 diff --git a/be/src/storage/index/snii/docs/perf/README.md b/be/src/storage/index/snii/docs/perf/README.md deleted file mode 100644 index 4b4982931b11bd..00000000000000 --- a/be/src/storage/index/snii/docs/perf/README.md +++ /dev/null @@ -1,157 +0,0 @@ -> **优先级修订（用户决定，2026-06-28，暂定）**：并发/锁相关工作（**T26** 及"searcher cache 自身是一把锁 / 锁竞争排序 / `_section_ranges` per-read 去锁"分析）**暂列为低优先级**。 -> -> **依据**：当前代码经实读确认**无锁内 IO**、无粗锁串行化查询；searcher cache 的锁有界（per-(query,segment) 2 次、临界区无 IO、已分片）；H1/H2 属**潜在/取决于共享是否生效**的隐患。 -> -> **注意**：**T04（DICT block 缓存）仍属 Batch 1 性能任务**，其实现须遵循 request-scoped 的并发安全约束（开销很小，**不构成对 T26 的硬依赖**）。下方自动生成的路线图/依赖图中若把 T26 列在 Batch 1，请以本修订为准。 -

-## 5. TDD 步骤（RED → GREEN → REFACTOR） - -**Step 1 (RED) — 引擎等价性失败先行** -在 `be/test/storage/index/snii_query_test.cpp` 新增 `SniiRegexpQueryTest` 套件（沿用文件，GLOB 自动纳入）。先写 `MatchesAnchoredLiteralTerm`：`regexp_query(idx,"order",&docids)` 期望 `{0..8999}`（"order" term 的全 docid）。此用例在当前 std::regex 实现下其实会通过——为制造真正的 RED，先写 **`InvalidPatternReturnsInvalidArgument`**：用 RE2 不支持但 std::regex 接受的 backreference pattern `(a)\1`，断言返回 `Status::InvalidArgument`。当前 std::regex 实现可能编译通过该 pattern（不返回 InvalidArgument）→ **FAIL**（RED）。 - -**Step 2 (GREEN) — 切 RE2 引擎** -按 §3.1 替换为 `re2::RE2` + `RE2::FullMatch` + `re.ok()` 错误路径。`(a)\1` 经 `re.ok()` 为 false → 返回 InvalidArgument。Step 1 转 GREEN，且既有 `RegexpQueryDoesNotExposeHiddenBigramTerms`（`snii_query_test.cpp:541-551`，`.*failed.*order.*` 期望空集）保持 GREEN（FullMatch 锚定语义等价）。 - -**Step 3 (RED) — 前缀收窄确定性断言失败先行** -写 `regex_enum_prefix` 的直测 `AnchoredGroupPrefixIsTightened`：`EXPECT_EQ(regex_enum_prefix("^(order)", re), "order")`，并对照 `EXPECT_EQ(literal_prefix_for_regex("^(order)"), "")`。当前不存在 `regex_enum_prefix` → 编译失败/FAIL（RED）。 - -**Step 4 (GREEN) — 实现前缀收窄** -按 §3.2 加 `internal::regex_enum_prefix`（PossibleMatchRange + 回退），在 `regexp_query` 用它替换裸 `literal_prefix_for_regex`。Step 3 转 GREEN。补端到端 `AnchoredGroupReturnsSameDocidsAsFullScan`：`regexp_query("^(order)")` 与已知 "order" docid 集相等，证明收窄后结果不变。 - -**Step 5 (REFACTOR)** -- 把 `regex_enum_prefix` 声明落 `internal/regex_prefix.h`，实现内提取公共前缀的 `std::mismatch` 逻辑（对齐 legacy 风格）； -- 更新 `regexp_query.h:12-14` 注释为 "matched with RE2::FullMatch (anchored both ends)"； -- 跑 `be-code-style`（clang-format）； -- 全程不改测试断言（仅在 Step 中新增），符合 §2 纪律。 -

-### 2. 影响的文件/函数 - -仅 `be/src/storage/index/snii/query/phrase_query.cpp`（匿名 namespace，reader-only）： - -- `Status BuildFlatPositionSource(const LogicalIndexReader& idx, const doris::snii::io::BatchRangeFetcher& round1, DocidSource* doc_source, const TermPlan& p, const std::vector& candidates, std::vector>* owners, PosSource* src)` — 当前 `:304-308` 私建 fetcher 并 `fetch()`。 -- `Status DecodeWindowedPositionSource(const LogicalIndexReader& idx, const TermPlan& p, DocidSource* doc_source, const std::vector& candidates, std::vector>* owners, PosSource* src)` — 当前 `:353-354` 私建 fetcher、`:390` `fetch()`、`:392-395` get+push owners。 -- `Status BuildPositionSourcesForCandidates(...)` — `:399-417` 顺序分派两个 builder。其调用方（`BuildPhraseExecutionState:947`、`CollectTailMatchesAtExpectedPositions:1121`）签名不变。 - -底层依赖（不改）：`doris::snii::io::BatchRangeFetcher`（`batch_range_fetcher.h:19-51`，`add/fetch/get/pending`，`get()` 返回指向 `phys_` 的稳定 `Slice`）；`doris::snii::reader::kSameTermCoalesceGap = 16*1024`（`windowed_posting.h:39`）；`windowed_window_range`、`idx.resolve_prx_window`（offset 计算，与在盘格式一一对应，不改）。 - -### 3. 变更设计 - -**核心**：把 PRX 阶段从「每 term 一个 fetcher + 一次 `fetch()`」重构为「整个短语共享一个 `BatchRangeFetcher`，两遍式：pass1 建 chunk 并 `add()` 所有 PRX range（记录回填句柄），单次 `fetch()`，pass2 回填 `chunk.prx` Slice」。 - -新增文件内辅助结构： -```cpp -struct PrxRangeAssignment { - size_t plan_index; // index into srcs - size_t chunk_index; // index within srcs[plan_index].chunks - size_t handle; // handle into the shared fetcher -}; -``` - -builder 改签名（去掉私建 fetcher，改为接收共享 fetcher + 装配记录 + plan_index）： -```cpp -Status BuildFlatPositionSource(idx, round1, doc_source, p, candidates, - size_t plan_index, - doris::snii::io::BatchRangeFetcher* prx_fetcher, - std::vector* assignments, - PosSource* src); -Status DecodeWindowedPositionSource(idx, p, doc_source, candidates, - size_t plan_index, - doris::snii::io::BatchRangeFetcher* prx_fetcher, - std::vector* assignments, - PosSource* src); -``` - -`BuildPositionSourcesForCandidates` 内： -```cpp -srcs->assign(plans.size(), PosSource{}); -auto prx_fetcher = std::make_unique(idx.reader(), - doris::snii::reader::kSameTermCoalesceGap); -std::vector assignments; -for (size_t i = 0; i < plans.size(); ++i) { // pass 1: build chunks + add ranges - if (plans[i].windowed) DecodeWindowedPositionSource(..., i, prx_fetcher.get(), &assignments, &(*srcs)[i]); - else BuildFlatPositionSource(..., i, prx_fetcher.get(), &assignments, &(*srcs)[i]); -} -if (prx_fetcher->pending() > 0) SNII_RETURN_IF_ERROR(prx_fetcher->fetch()); // single round -for (const auto& a : assignments) // pass 2: assign slices - (*srcs)[a.plan_index].chunks[a.chunk_index].prx = prx_fetcher->get(a.handle); -if (!assignments.empty()) owners->push_back(std::move(prx_fetcher)); // keep alive -``` - -各 builder 内部行为保持： -- flat `pod_ref`：`resolve_prx_window` 得 (poff,plen)，`prx_fetcher->add(poff,plen)` 取 handle；按现逻辑构造 chunk（dd 仍从 round1 解码、`SelectCandidateDocsForPrx` 仍只对 docids 运算，不依赖 prx 字节）；仅当 chunk 被 push 时记录 `assignments.push_back({plan_index, chunk_index_before_push, handle})`。**为保持与现实现字节等价**：现实现对每个 pod_ref term 无条件 `fetch()`（即便 chunk 最终为空），故 `add()` 同样无条件执行；chunk 为空时只是不记录 assignment（多读的字节与现行为一致）。 -- flat inline（`!p.pod_ref`）：保持 `chunk.prx = Slice(p.entry.prx_bytes)`，**不 add 任何 range**（保留 `:310` 零 IO 快路径）。 -- windowed：保留 `ChunkMayContainCandidate` 过滤、`SelectCandidateDocsForPrx`、`windowed_window_range`；把现有 `prx_fetcher->add(range.prx_off, range.prx_len)` 改为对共享 fetcher 调用，`chunk_index = src->chunks.size()`（push 前），记录 `assignments`，删除本函数内的 `fetch()`/get/owners-push。 - -**两遍顺序正确性**：候选选择（`SelectCandidateDocsForPrx` / `docids_are_final_candidates` 分支）决定 candidate 落在哪个 window，必须先于 range 计算——pass1 内部即按此顺序（先 select 再 `windowed_window_range` 再 add），与现实现完全一致。所有 range 计算只读 prelude（round1 已 open）与 docids，**不读 prx 字节**，故可全部先 `add` 再统一 `fetch`。 - -**coalesce_gap 选择**：共享 fetcher 用 `kSameTermCoalesceGap`（=16KB，与现 windowed 路径一致）。验证器纠正：保留 same-term 窗口内合并；跨 term 的 PRX span 在 posting region 中相距甚远（各 term 为 [prx][frq] 连续大段），不会过度合并到把中间 frq 读进来；批量收益来自 `read_batch` 的波内并发，而非合并。**不得**为强制跨 term 合并而抬高 gap（会过读 term 间的 frq）。flat 路径原 gap=0、每 term 仅一个 prx range（单 range 无可合并内容），并入共享 fetcher 后即便相邻 term 的 prx 落入 16KB 内被合并，`get()` 经 `sub_offset` 仍返回正确子切片，最多多读 ≤gap 字节，正确性不受影响。 - -**FORMAT-COMPATIBILITY**：reader/writer-only，零在盘变更。PRX offset 经 `resolve_prx_window`/`windowed_window_range` 与现实现逐字节同算。 - -**CONCURRENCY**：N/A，无共享可变状态。共享 fetcher 是 **request-scoped**（生命期挂在 `PhraseExecutionState::owners` 或 tail 路径局部 `owners`），单线程顺序使用；`get()` 返回的 Slice 指向 `phys_` 缓冲，`fetch()` 后稳定，与现「每 term fetcher 保活」语义相同。并发只发生在 `read_batch` 内部（S3 `std::async` 波），fetcher 本身不跨线程。共享 `LogicalIndexReader` 读路径仍为 const 无锁；本改动不新增任何 per-reader 可变状态，无 NO-IO-UNDER-LOCK 风险（无锁）。 - -### 4. 依赖 - -- depends_on：无（Batch 1 独立）。 -- 复用既有基础设施：`BatchRangeFetcher`（已存在 `add/fetch/get/pending` 语义恰好支持两遍式）；测试侧 `MemoryFile`+`build_reader`（`snii_query_test.cpp:53-279`）、`MeteredFileReader`/`IoMetrics`（`metered_file_reader.h`/`io_metrics.h`）。 -- 不产出新共享基础设施。 - -### 5. TDD 步骤（RED → GREEN → REFACTOR） - -**Step 1 — RED（性能确定性）**：在 `snii_query_test.cpp` 新增计数装饰器 `BatchRoundCountingReader`（实现 `FileReader`，`read_batch` 自增 `batch_rounds_` 后委托 inner，`read_at` 委托 inner）。新增辅助 `build_slim_pod_ref_phrase_reader`（自定义 `SniiIndexInput`：3 个 df≈400、单 position 的重叠 term，确保 slim 非 windowed 且序列化 >256B → `pod_ref`；位置安排成可命中短语，保证候选非空）。写 `TEST(SniiPhraseQueryTest, PhraseQueryIssuesSinglePrxBatchRound)`：包 `BatchRoundCountingReader`，跑 3-term `phrase_query`，断言 `reader.batch_rounds() == 2`（round1 一次 + PRX 阶段一次；conjunction 对 flat term 0 次）。**当前代码该值为 4**（PRX 阶段每 term 一次）→ FAIL。 - -**Step 2 — GREEN**：按 §3 重构三个函数为共享 fetcher 两遍式。最小改动使 PRX 阶段只 `fetch()` 一次 → 计数变 2，测试转 GREEN。 - -**Step 3 — RED→GREEN（功能等价）**：写 `TEST(SniiPhraseQueryTest, ThreeTermPhraseMatchesAcrossSharedPrxFetch)`，对 windowed 3-term 短语断言结果集与逐 term 取数路径一致（全量 `EXPECT_EQ`）。重构前后均应 GREEN（等价性保护）；若实现破坏句柄回填会 FAIL。 - -**Step 4 — REFACTOR**：抽出 `record_prx_assignment(...)` 小工具消除 flat/windowed 两处重复；确认现存 `WindowedPhraseQueryKeepsCorrectCandidateOrdinals`、`WindowedPhrasePrefixQueryKeepsCorrectCandidateOrdinals`、`SingleTailPhrasePrefixUsesStreamingPhrasePath`、`MultiTailPhrasePrefixFiltersTailPrxByExpectedDocs`、`TwoTermPhrase*` 全绿（不改测试）。`be-code-style` 过 clang-format。 -

-**Phase 2（无锁，并行）— 物理读**： -- 为每个 seg 准备目标缓冲：`single` 段直接读入 `(*outs)[sorted[begin].index]`（**F27 单段直读，零临时、零二次拷贝**）；多段合并组读入该 seg 独占的临时 `std::vector`（存于 `std::vector> tmp_bufs`，与 seg 一一对应）。 -- **每段独占一份 `io::FileCacheStatistics`**（`std::vector seg_stats(segs.size())`），其 `io_ctx.file_cache_stats` 指向自己的槽——这样底层 Doris `read_at` 对 cache 计数的写入落在**不相交内存**，消除 verifier 注（1）所述的非原子 stats 竞争。 -- 派发：`size_t kMaxConcurrent = 16`，按波次提交到 `ExecEnv::GetInstance()->buffered_reader_prefetch_thread_pool()`（`exec_env.h:258`），用 `doris::CountDownLatch`（`util/countdown_latch.h`）join；每段 Status 写入独占的 `std::vector<::doris::snii::Status> seg_status`。**首错语义**：join 后取第一个非 OK。 -- **兜底/seam**：新增私有静态 `ThreadPool* _io_pool_for_test`（默认 nullptr）。实际 pool 选择：`_io_pool_for_test ? _io_pool_for_test : (ExecEnv::ready() ? ExecEnv::GetInstance()->buffered_reader_prefetch_thread_pool() : nullptr)`。当 pool==nullptr 或 `segs.size()<=1` 时走**串行兜底**（避免微批调度开销、并保证无 ExecEnv 的环境可用）。新增 `static void set_io_thread_pool_for_test(ThreadPool*)` 供测试注入本地 `ThreadPool`。 - -**Phase 3（串行）— 散射与计数**： -- 多段合并组：从 `tmp_bufs` 按 `pos = sorted[i].offset - seg.offset` `assign` 到 `(*outs)[sorted[i].index]`（沿用 :273-278）。单段组已直读，无需散射。 -- 合并 `seg_stats[*]` 到真实 `_current_io_ctx()->file_cache_stats`（新增 `static void merge_file_cache_statistics(io::FileCacheStatistics* dst, const io::FileCacheStatistics& src)`，逐字段相加，含 `inverted_index_snii_section_*` 六个 `std::array` 元素级相加；`io_common.h:62-123` 全为 int64/int64-array，可机械相加）。 -- 调用 `_record_read_stats(request_bytes, read_bytes, range_read_count=segs.size(), serial_read_rounds=num_waves)`，其中 **`num_waves = ceil(segs.size()/kMaxConcurrent)`**——这是 F19 的核心可验证指标：K(≤16) 段从原来的 `serial_read_rounds==K` 降为 `==1`。该计数语义与 `MeteredFileReader`（"at most one serial round"）一致，**与 executor 是否真起线程无关**，故确定性。 - -**FORMAT-COMPATIBILITY 结论**：reader/writer-only，零在盘字节变更（不触及任何序列化格式）。 -**CONCURRENCY 结论**： -- `read_batch` 仅用局部状态 + 共享 `_reader`（对不相交 range 的并发 `read_at` 安全，依据 verifier 注（2）与 S3FileReader 既有 16 路实践）+ `_section_ranges`（Phase 1 `shared_lock` 只读）。 -- **NO-IO-UNDER-LOCK 保持**：分类全部在 Phase 1 串行持锁完成，worker 仅做 `_read_at`，**不触碰 `_section_ranges_mutex`**。 -- 共享可变状态：本任务**未给共享 reader 新增任何可变成员**（`seg_stats`/`tmp_bufs`/latch 均为 per-call 栈局部）；stats 经 per-seg 私有槽 + 串行合并消除竞争。disjoint outs 槽无别名。 -- 这与 `CONCURRENCY.md` 的红线（§二/§五）一致；不涉及 T04 的 per-reader 缓存隐患。 - -## 4. 依赖 - -- **依赖**：BE `buffered_reader_prefetch_thread_pool`（`exec_env.h:258`，已存在）；`doris::CountDownLatch`（已存在）。无对其他 SNII 任务的硬依赖。 -- **提供**：为所有经 `BatchRangeFetcher::fetch()` 的查询路径（boolean/phrase/docid_conjunction/scoring/windowed）透明提速，无需改这些调用方。 - -## 5.

-**Step 2 — RED（F27 单段直读，去临时缓冲）**：`TEST(DorisSniiFileReaderTest, SingleSegmentGroupReadsWithoutDoubleBuffer)`。用注入的 `CountingFileReader`（mock，read_at 把目标 buffer 的 `data()` 指针记录下来）或更简单：在单段路径断言"输出 vector 的内容正确且物理读次数 == 段数"。直接断言**无二次拷贝**较难，用替代确定性指标：`out` 内容正确 + `recording_reader->reads().size() == segs.size()`（单段组物理读=段数）。先以"现状仍走 temp+assign，但功能正确"为基线；RED 体现在 §7 的 alloc-count 测试（见下）。 -- 更强的确定性 RED：`TEST(..., SingleSegmentGroupReadsInPlace)` 用一个 `InPlaceProbeReader`：其 `read_at_impl` 记录 `result.data` 指针；测试断言该指针 == `outs[index].data()`（即直读进 outs，未经临时缓冲）。当前实现读入局部 `bytes` → 指针不等 → **FAIL**。 -**GREEN**：单段组直读 `(*outs)[index]`。 -**REFACTOR**：把"目标缓冲选择"抽成小函数。 - -**Step 3 — RED（F27 去重排）**：`TEST(..., DoesNotResortAlreadySortedRanges)`——用计数比较器较难直接测；改为结构断言：传入已排序 ranges，结果正确（等价性）。重排去除属纯净化，主要靠"行为等价"测试（Step 5）+ `std::is_sorted` 守卫的代码审查覆盖，不单列强 RED。 -**GREEN**：`if (!std::is_sorted(...)) std::sort(...)`。 - -**Step 4 — RED（并发/线程安全，注入 pool）**：`TEST(DorisSniiFileReaderConcurrencyTest, ParallelSegmentReadsAreThreadSafe)`：用 `ThreadPoolBuilder` 建本地 4 线程 pool，`set_io_thread_pool_for_test(pool)`；构造 8 个不相交段的 batch，调用 read_batch，断言全部输出字节正确 + `recording_reader->reads().size()==8` + `serial_read_rounds==1`。在 `BUILD_TYPE_UT=TSAN` 下应无告警（per-seg 私有 stats、disjoint outs、mutex 保护的 _reads）。RED：在未实现并行前，注入 seam 不存在 → 编译失败/断言失败。 -**GREEN**：实现 Phase 2 派发 + seam。 -**REFACTOR**：抽 `dispatch_segment_reads(pool, ...)`。 - -**Step 5 — RED（等价性 new==old）**：`TEST(..., ParallelPathMatchesSerialPath)`：同一组 ranges，分别用 `set_io_thread_pool_for_test(nullptr)`（串行兜底）与注入 pool（并行）跑，断言两次 `outs` 逐 vector `EXPECT_EQ` 全等。保证并行不改变结果。 - -每步均"业务代码 + UT + 验证"自闭环。 -

-## 1. 目标与背景 - -**问题（finding 映射）**： -- **F21 [MEDIUM]**：生产构建路径上每个 token 都在 intern lookup 处构造一个临时 `std::string`。`spimi_term_buffer.cpp:223` 为 `auto it = intern_.find(std::string(term));`，而 `intern_` 声明为 `std::unordered_map`（`spimi_term_buffer.h:306`，默认 `std::hash`/`std::equal_to`，无 `is_transparent`），所以用 `string_view` 探测必须先把它物化成 `std::string`。对 >SSO（15B）的 term（每个 phrase bigram 至少 20B marker，见 `phrase_bigram.h:10-13`，实测 marker = 20 字节；CJK/长 token 亦然）这是 per-token 的 malloc+memcpy+free。该开销对"已见 term"的常态命中也照付（`find` 总要先建探测键）。 -- **F03 [HIGH]**：每个 distinct term 字符串被存两份。`spimi_term_buffer.cpp:226-228`：`owned_vocab_.emplace_back(term)` 存第 1 份，`intern_.emplace(owned_vocab_.back(), term_id)` 把字符串作为 map key 再拷一份（第 2 份 owned `std::string`），加上 unordered_map 节点开销（~16B 节点 + 4B value）。对 phrase-bigram/高基数列（数百万 distinct bigram）这是数百 MB 的可避免重复，且全程不可 spill（`spill_to_run`/`merge_runs` 只释放 arena 与 slot，见 `:476`、`:522-524`；`resident_bytes()` `:96-103` 也不计 vocab），是 gate-2 cap 管不住的常驻 peak-RAM 源。 - -**生产命中确认**：`snii_index_writer.cpp:51` 用 OWNED-vocab 构造函数建 `SpimiTermBuffer`；每个分词 token 经 `:178` `add_token(term, ...)`、每个相邻 phrase bigram 经 `:153-155` `add_token(make_phrase_bigram_term(...), ...)` 喂入，全部走 `add_token(string_view)`（即 `cpp:208`）。header 宣传的 BORROWED-vocab 整数 id 快路径在生产中无任何调用者（F21/F03 验证器均确认），故 `cpp:223` 的临时串 + 双存对每个 token/distinct term 真实发生。 - -**预期收益**：去掉每 token 的临时 `std::string`（>SSO term 省一次 malloc/memcpy/free），构建 CPU + allocator churn 下降（phrase/CJK 工作负载最明显）；每个 distinct term 字符串只存一份，去掉 map 的 owned-string key，显著降低高基数/bigram 索引的常驻 vocab 内存。**纯 reader/writer-only 内存内改动，零在盘字节变更，查询路径不受影响。** - -## 2. 影响的文件/函数 - -仅一个生产文件 + 其头文件 + 一个新建测试文件： - -- `be/src/storage/index/snii/writer/spimi_term_buffer.h` - - 成员声明 `:306` `std::unordered_map intern_;`（将改类型）。 - - `:303-304` `vocab_` / `owned_vocab_`（保持不变：`owned_vocab_` 仍是 `std::vector`，是 vocab 的唯一一份存储）。 - - `vocab() const` `:251` 返回 `const std::vector&`（**保持签名不变**）。 - - 新增 `namespace doris::snii::writer::testing` 的计数器声明（测试 seam）。 -- `be/src/storage/index/snii/writer/spimi_term_buffer.cpp` - - `add_token(std::string_view, uint32_t, uint32_t)` `:208-234`（lookup + 插入逻辑改写）。 - - owned-vocab 构造函数 `:62-70`（绑定 intern_ 的 functor 到 `&owned_vocab_`）。 - - 新增计数器定义 + 在 `owned_vocab_.emplace_back` 处自增。 -- 不动：`MergeRuns`（`spill_run_codec.h:177` 签名 `const std::vector& vocab`）、`drain_sorted`/`drain_to_writer`/`merge_runs`/`sorted_ids`/`ensure_string_rank`（它们均经 `vocab()` 取 `std::vector&`，因 `owned_vocab_` 类型不变而全部无感）。 - -**关键设计约束**：`vocab()` 返回类型被 `MergeRuns(run_paths_, vocab(), ...)`（`cpp:530`）与 borrowed 模式共享。因此**不能**把 `owned_vocab_` 改成 `std::deque`（F03 验证器 caveat 2 指出这会破坏 vocab()/MergeRuns，"非 drop-in"）。本方案改的是 **intern_ 的 key 类型**而非 vocab 存储，从而绕开该接口重整问题。 - -## 3. 变更设计 - -### 3.1 数据结构：intern_ 由"string-keyed map"改为"id-keyed transparent set" - -把 `std::unordered_map intern_` 替换为以 **term-id（uint32_t）为 key** 的 set，配套一对**透明（is_transparent）**的 hash/equal functor，functor 持有 `&owned_vocab_`，对存储的 id 解引用到 `owned_vocab_[id]` 再按字符串内容 hash/比较： - -```cpp -// spimi_term_buffer.h（声明在类内 private，functor 可定义为内嵌或文件内） -struct OwnedVocabHash { - using is_transparent = void; - const std::vector* vocab = nullptr; - size_t operator()(std::string_view s) const noexcept { -

return std::string_view((*vocab)[a]) == s; - } -}; -std::unordered_set intern_; -``` - -- **同时根治 F21 与 F03**：F21 —— `find(term)` 用 `string_view` 异构探测，零临时串、零 malloc；F03 —— set 只存 4B id，字符串只在 `owned_vocab_` 存一份，map 的 owned-string key 彻底消失。 -- **C++20 支持**：BE 为 C++20（`be/CMakeLists.txt:350`），P0919/P1690 为 unordered 容器提供异构 `find`，要求 **hash 与 equal 都透明**（两者都加 `using is_transparent = void;`，缺一不可 —— F21/F03 验证器均明确强调）。hash 始终以 `string_view` 计算，保证 stored-id 与 probe-string_view 对相同内容产生相同 hash，已有条目可被找到。 - -### 3.2 add_token(string_view) 改写 - -```cpp -void SpimiTermBuffer::add_token(std::string_view term, uint32_t docid, uint32_t pos) { - if (vocab_ != &owned_vocab_) { /* 保持原 reject 逻辑不变 :216-222 */ return; } -

intern_.insert(term_id); // 只存 id；hash 读 owned_vocab_[term_id]（已 push_back，合法） - slot_of_.push_back(0); - } else { - term_id = *it; - } - accumulate(term_id, docid, pos); -} -``` - -### 3.3 指针稳定性（关键正确性论证） - -set **存的是 id（值类型 uint32_t），不存指针/`string_view`**。因此 `owned_vocab_.emplace_back` 触发的 vector 扩容**不会**使任何已存条目失效：扩容后 hash/eq 仍按当前 `owned_vocab_[id]` 重新读取内容。这正是为何无需把 `owned_vocab_` 换成 pointer-stable 容器，从而完整规避 F03 验证器 caveat 1/2。插入顺序：先 `emplace_back`（使 `owned_vocab_[term_id]` 有效），再 `insert(term_id)`（其 hash 解引用该项）—— 顺序正确。 - -### 3.4 构造期绑定 - -owned-vocab 构造函数（`cpp:62-70`）体内把 `intern_` 的 functor 绑到 `&owned_vocab_`： -```cpp -intern_ = decltype(intern_)(0, OwnedVocabHash{&owned_vocab_}, OwnedVocabEq{&owned_vocab_}); -``` -borrowed 构造函数同样绑定（无害，借用模式下 `add_token(string_view)` 在触达 intern_ 前即 reject，functor 永不被解引用）。成员声明顺序 `owned_vocab_`(304) 先于 `intern_`(306)，构造体内绑定与声明序无冲突。 - -### 3.5 FORMAT-COMPATIBILITY 结论 - -**reader/writer-only，零在盘字节变更。** `intern_`/`owned_vocab_` 纯内存构建态；run 以 term-id 编码、k-way merge 以 vocab 字符串排序（内容不变）；dict 存 `TermPostings.term`，其内容与容器实现无关。改前后 term-id 分配顺序（first-seen）与 finalize 输出**逐字节相同**。 - -### 3.6 CONCURRENCY 结论 - -**N/A，无共享可变状态。** 每个 `SniiIndexColumnWriter` 独占自己的 `SpimiTermBuffer`（`snii_index_writer.cpp:51`），单线程喂 token，不跨线程共享（F21/F03 验证器均确认）。本任务不触及共享 reader 状态、不引入锁、不在锁内做 IO/解压。CONCURRENCY.md 的 H1/H2 与本任务无关。 -

-**Step 2（GREEN — 最小实现）** -- 按 §3.1/§3.2/§3.4 把 `intern_` 改为 id-keyed transparent set，`find` 改用 `string_view`，**删除** `std::string(term)` 临时串（连同其计数自增点）。保留 `emplace_back` 处的计数自增。 -- 重跑 Step 1：计数 = 1（仅 emplace 一次）→ **PASS**。 - -**Step 3（RED→GREEN — 正确性等价）** 写 `VocabAssignsIdsInFirstSeenOrder` 与 `FinalizeProducesExpectedPostings`： -- 喂一组已知 token 序列（含重复 term、>SSO bigram term、空 vocab 起步），`finalize_sorted()` 全量对比期望 `TermPostings`（term/docids/freqs/positions）。先确认在改动前后均 PASS（characterization，守护重构不改语义）。 - -**Step 4（REFACTOR）** -- 把内嵌 functor 与计数 seam 整理到清晰位置；`be-code-style` 跑 clang-format；`static_assert(std::is_same_v)` 固化"单存"结构事实。 -- 全量 `./run-be-ut.sh --run --filter='SniiSpimiTermBufferTest.*'` + 既有 `SniiPhraseQueryTest.*`（确保 writer 端到端无回归）绿。 -

-**回滚**：改动集中于单一文件对（`spimi_term_buffer.h`/`.cpp`）的 `intern_` 类型、`add_token(string_view)` 与构造函数三处，且零在盘格式变更、零接口签名变更（`vocab()`/`MergeRuns` 不动）。`git revert` 该提交即可完全恢复旧 `unordered_map` 路径，无数据迁移、无兼容性后果；新建测试文件可独立保留或一并撤回。 \ No newline at end of file diff --git a/be/src/storage/index/snii/docs/perf/T06-phrase-nterm-bigram-candidates.md b/be/src/storage/index/snii/docs/perf/T06-phrase-nterm-bigram-candidates.md deleted file mode 100644 index 929d2c460571a9..00000000000000 --- a/be/src/storage/index/snii/docs/perf/T06-phrase-nterm-bigram-candidates.md +++ /dev/null @@ -1,117 +0,0 @@ -## T06 — >=3 词短语用 bigram 交集生成候选 -

-**问题**: `phrase_query()` 仅对 `terms.size()==2` 走隐藏 bigram posting（`TryTwoTermPhraseBigram`，`phrase_query.cpp:1169-1173` 调用 `:137-166`）。对 n>=3，代码经 `BuildPhraseTermMapping`→`plan_terms(unique_terms)`（`:1180-1185`）→`ExecutePhrasePlans`（`:1187`）→`BuildPhraseExecutionState`→`internal::build_docid_only_conjunction`（`:944-945`）。该 per-term 交集只受最小词 df 约束，因此含常见词的短语（如 "the brown fox"）候选集 ≈ 含全部词的文档（≈ 较稀有词的 df），随后 `BuildPositionSourcesForCandidates`（`:947-948`）要为这一巨大候选集逐窗抓取/解码 PRX——在冷 S3 上每个多余位置窗口都是一次远程 round。 - -**已具备的数据**: writer 对每个「相邻且位置连续的可索引 token 对」无条件写 `make_phrase_bigram_term(left,right)` 且携带左词位置（`snii_index_writer.cpp:102-167`，尤其 `:158-163`），并在 `finish()` 中只要 `_has_positions && _rid>0` 就写 sentinel（`:256-258`）。故对任何「具备位置」的较新索引，相邻 bigram 与 sentinel 必然存在——这是纯读侧可利用的现成数据。 - -**预期收益**: 对 n>=3 且含常见词的短语，用 n-1 个相邻 bigram 的 docid 交集生成候选（每个 bigram 的 df<=min(df(t_i),df(t_{i+1}))），候选集是短语真匹配的严格超集，再跑现有位置校验。候选集显著缩小 → 为每个（尤其高 df windowed）词抓取/解码的 PRX 窗口数与字节数大幅下降。最显著于冷 S3。 - -### 2. 影响的文件/函数 -

-### 3. 变更设计 - -**算法（phrase_query n>=3 分支）**: -1. 沿用 `:1166` `has_positions` 检查与 `:1180-1186` 的 `BuildPhraseTermMapping`+`plan_terms(unique_terms, need_positions=false)`+`all_present` 检查（任一词缺失→空，短语必不匹配）。 -2. `phrase_bigram_enabled(idx,&enabled)`。 -3. `ShouldUsePhraseBigram`: 返回 true 当且仅当 (a) `enabled`（sentinel 存在=较新索引，**格式兼容门**），且 (b) 所有 `terms[i]` 满足 `is_phrase_bigram_indexable_term`（与 writer 仅对可索引词建相邻 pair 的语义对齐，见 `snii_index_writer.cpp:118-120`），且 (c) **至少一个 plan 为 windowed**（df>=512；对应验证器 caveat(5)：全稀疏词时 per-term 交集已极小，读 n-1 个 bigram 反而可能略差，故回退）。 -4. 若不启用 → 走原 `ExecutePhrasePlans(... , initial_candidates=nullptr)`（与今日完全一致的回退路径）。 -5. 若启用 → `BuildBigramPhraseCandidates`： - - 由**原始有序 terms**构造相邻 pair `(terms[i],terms[i+1]), i∈[0,n-2)`（**用有序 terms 而非 unique_terms**，正确处理重复/重叠词，验证器 caveat(3)）。 - - 对每个 pair `resolve_query_term(make_phrase_bigram_term(...))`。若某 pair **未找到**：因 sentinel 已启用且两词均可索引，writer 必然会为任何曾相邻连续出现的 pair 建 bigram，故「未找到 ⟺ 该 pair 从未连续出现 ⟺ 短语必不匹配」→ `candidates` 置空、`usable=true` 返回（验证器 caveat(2) 的 df=0 早空等价）。 -

-**为何结果不变（正确性核心）**: 若短语在某 doc 的位置 p..p+n-1 出现，则每个相邻 pair 的 bigram 在该 doc 必存在 → 该 doc ∈ 所有 bigram posting 的交集 → ∈ candidates。故 candidates ⊇ 真匹配集；随后的 `BuildPhraseExecutionState(initial=candidates)`→`filter_docids_by_conjunction`→`BuildPositionSourcesForCandidates`→`EmitPhraseStreaming` 为**完全未改动**的精确位置校验，输出与旧路径逐位相等（两个 bigram 同现不证明它们链式相接，故校验仍必需——验证器明确指出）。 - -**`BuildPhraseExecutionState` 改造**: 形参增 `const std::vector* initial_candidates`。`initial_candidates==nullptr` → 原 `build_docid_only_conjunction(idx,*round1,*plans,&state->candidates,&doc_sources)`；否则 → `filter_docids_by_conjunction(idx,*round1,*plans,*initial_candidates,&state->candidates,&doc_sources)`（范式同 `:1115`）。其余（`round1->fetch`、`open_preludes(need_positions=true)`、`BuildPositionSourcesForCandidates`）不变。 -

-### 5. TDD 步骤（RED → GREEN → REFACTOR） - -**RED-1（等价性会暴露 bug 的前提先建数据）**: 扩展 `build_reader` 的 `include_phrase_bigrams` 分支（`snii_query_test.cpp:260-266`），新增 `make_phrase_bigram_term("order","ordinal")`={{5000,{0}},{7000,{0}}} 与（重复词用例）`make_phrase_bigram_term("repeat","repeat")`=全 9000 docs。写测试 `SniiPhraseQueryTest.ThreeTermPhraseUsesBigramCandidates`：在含 bigram 的 reader 上 `phrase_query({"failed","order","ordinal"})` 期望 `{5000,7000}`。此时 n>=3 尚无 bigram 路径——**断言会因为读放大对照子句失败**（见步骤的性能断言部分），但结果断言此刻已 PASS（旧路径正确）。为获得真正 RED，先写**性能对照断言**（bigram reader 的 `read_bytes` < 无 bigram reader 的 `read_bytes`），当前两者相等 → FAIL。 - -**GREEN-1**: 在 `phrase_query` n>=3 分支接入 `ShouldUsePhraseBigram`+`BuildBigramPhraseCandidates`，并为 `BuildPhraseExecutionState`/`ExecutePhrasePlans` 加 `initial_candidates`。最小实现使性能对照断言转 GREEN（候选集由 9000 缩到 2，PRX 窗口抓取从每词约 9 窗降到约 2 窗）。 - -**RED-2**: 写 `SniiPhraseQueryTest.ThreeTermBigramMatchesPerTermPath`（等价性）：对同一组短语，分别在 `include_phrase_bigrams=true`（bigram 路径）与 `false`（per-term 回退）两 reader 上查询，`EXPECT_EQ` 两者结果且都等于黄金 `{5000,7000}`。先以一个 bug 注入版（例如用 unique_terms 而非有序 terms 建 pair）跑出对「重复词短语」的 FAIL，确认测试有效；恢复后 GREEN。 - -**RED-3**: 写 `SniiPhraseQueryTest.ThreeTermBigramMissingPairIsEmpty`：`phrase_query({"failed","order","needle"})`（不向 fixture 添加 bigram(order,needle)）期望 `{}`，且与 per-term 路径等价。当前若实现把「未找到 pair」误当作回退而非早空，需保证仍返回正确空集（真匹配本就为空）→ 作为正确性回归守卫。 - -**RED-4**: 写 `SniiPhraseQueryTest.ThreeTermNonIndexableFallsBackToPositions`：`phrase_query({"failed","order","123"})`（"123" 非可索引）期望与 per-term 路径等价（此例为 `{}`）。验证 `ShouldUsePhraseBigram` 门控回退。 - -**RED-5**: 写 `SniiPhraseQueryTest.ThreeTermBigramAbsentSentinelFallsBack`：在 `include_phrase_bigrams=false`（无 sentinel）reader 上 `phrase_query({"failed","order","ordinal"})` 期望 `{5000,7000}`（走 per-term 回退）。守卫旧索引格式兼容。 - -**RED-6（重复词）**: `SniiPhraseQueryTest.ThreeTermRepeatedBigramKeepsAllDocs`：`phrase_query({"repeat","repeat","repeat"})` 期望 0..8999 全集（与现 `RepeatedTermPhraseUsesCachedPostingSpan` 黄金一致），验证有序 pair (repeat,repeat)×2 交集与重复词位置校验正确。 - -**REFACTOR**: 抽出 `ShouldUsePhraseBigram`/`BuildBigramPhraseCandidates` 小函数（<50 行），English 注释说明「候选=相邻 bigram 交集=真匹配超集，校验保精确」；过 `be-code-style`。确认所有既有 `SniiPhraseQueryTest.*`（含 2 词 bigram、phrase-prefix、windowed、sparse）保持 GREEN。 -

-`locate_window`（`be/src/storage/index/snii/format/frq_prelude.cpp:445-468`）每次做：① 在 super-block 目录 `sb_last_docid_` 上 `std::lower_bound`（`:454`，~log n_super），② 从 `lo = sb*group_size`（`:458`，G 默认 64，`frq_prelude.h:124`）起**重新线性扫描**至多 G 个 `windows_[i].last_docid`（`:460-466`）。由于每次都从 super-block 块首重启扫描，映射到同一组的候选会反复重扫该组 → 整体 **O(C·(log n_super + G))**，且每次触碰 ~104–112B 的 `WindowMeta` 行（`last_docid` 在偏移 0）。候选与窗口**都已升序**，本质是一个被当成 C 次独立查找来执行的有序归并。 - -**Finding 映射 / 修订后严重度**： -- **F05 [MEDIUM]**（cross-cutting-systems，`需改格式: False`，`needs-nuance`）：算法低效真实存在，但验证器把"每窗一次 cache-miss"的表述下调——一个 super-block 组 = 64×~104B ≈ 6.6KB，**L1 常驻**，重扫主要烧 CPU 比较而非 cache-miss。被验证器从 high/medium 下调为 **MEDIUM**。 -- **F42 [LOW]**（query-postings-ops，同位置，同类问题，重复指出"应为 two-pointer 归并"）：验证器评 **LOW**，因 `should_scan_all_windows`（`docid_conjunction.cpp:516-524`）已把候选数 C 上界钳到 `window_count*64`，最坏 ~10⁵ 次整数比较（数十 µs），且这是纯 CPU 选择步，其后的 **PFOR 解码 + （可能远程的）窗口字节抓取才是主导**（`collect_windowed_docids_only:650-675`）。 - -**真实热点形状（必须如实反映）**：仅在"多个 windowed 高频词（df≥512）+ 中等密度候选"的 phrase / MATCH_ALL 形状才显著——conjunction 按 `ascending_df_order` 处理，第一个词（k==0）走 `all_windows` 分支（`:685`），**只有非首位的 windowed 词**且候选数落在 `should_scan_all_windows` 阈值**之下**的中等密度带，才走 `select_covering_windows`（`:691`）。 - -**预期收益与口径**：把窗口定位从 O(C·(log n_super + G)) 降为 **O(C + N)** 的单调双指针，每次只比较 4B 的 `last_docid`（可选 packed 数组）。**收益主要是窗口比较次数（query CPU）的下降，不是 wall-clock 主导项**（解码/IO 主导）。因此本任务的**确定性单体证据**为两条不变量： -1. `probe_count`（窗口 `last_docid` 比较次数）从随 G 增长的 O(C·G) 降为 **`probe_count ≤ C + N`** 且与 G 无关； -2. 选出的覆盖窗口集合相对旧 `locate_window`-per-candidate 实现**逐元素相等（同序、同去重）**。 - -packed `win_last_docid_` 的 cache-locality 收益**无法确定性证明**（cache-miss 下降不可机验），其单测只能验证**位级等价 + 不改变窗口集合**，wall-clock 仅作 report-only 微基准旁证，**不作 CI 门禁**。 - -## 2. 影响的文件/函数 - -**头文件** `be/src/storage/index/snii/format/frq_prelude.h` -- 现有：`Status FrqPreludeReader::locate_window(uint32_t docid, bool* found, uint32_t* w) const;`（`:163`，返回"首个 `last_docid ≥ docid` 的窗口"；`docid > windows_.back().last_docid` 时 `*found=false`）。**保留**（公开 API + 等价性测试 oracle）。 -- 现有：`Status FrqPreludeReader::window(uint32_t w, WindowMeta* out) const;`（`:157`，整结构体拷贝；不动）。 -- 现有：`uint32_t n_windows() const`（`:144`）、`std::vector sb_last_docid_;`（`:173`）、`std::vector windows_;`（`:175`，`open()` 后不可变）、`uint32_t group_size_`（`:168`）、`uint32_t n_super_`（`:169`）。 -- 新增（本任务）：packed `std::vector win_last_docid_;`（private，in-memory only）；inline 访问器 `uint32_t window_last_docid(uint32_t) const`；const 成员 `void select_covering_windows(const std::vector&, std::vector*) const`；自由函数 `select_covering_windows_cursor(...)`（隔离可测核心）；`namespace doris::snii::format::testing { uint64_t window_probe_count(); void reset_window_probe_count(); }`。 - -**实现** `be/src/storage/index/snii/format/frq_prelude.cpp` -- `FrqPreludeReader::open`（`:404-434`）：在 `decode_all_blocks`（`:432`）填好 `windows_` 后，紧随 `sb_last_docid_` 的构建（`:429-431`）**并行构建 `win_last_docid_`**。 -- `FrqPreludeReader::locate_window`（`:445-468`）：仅在 level-2 扫描循环（`:460-466`）插入 `++g_window_probes` 计数 seam（行为不变，保留为 oracle）。 - -**调用方** `be/src/storage/index/snii/query/docid_conjunction.cpp` -- `Status select_covering_windows(const FrqPreludeReader& prelude, const std::vector& candidates, std::vector* windows)`（`:497-514`，匿名命名空间）：**删除**，逻辑迁入 `FrqPreludeReader`。 -- `collect_docids_only`（`:679`）在 `:691` 处的调用 `SNII_RETURN_IF_ERROR(select_covering_windows(p.prelude, *candidates, &windows));` 改为 `p.prelude.select_covering_windows(*candidates, &windows);`（成员纯内存、不可失败，去掉 `SNII_RETURN_IF_ERROR`）。 -- 下游 `collect_windowed_docids_only`（`:620-677`）消费 `windows`（`:629` 起以 `p.prelude.window(w,&meta)` 顺序遍历 + `find_candidate_range` 的单调 `candidate_search_begin`），**要求 windows 升序**——游标天然保证，契约不变。 - -**数据结构** `WindowMeta`（`frq_prelude.h:86-115`）：~104–112B；`last_docid`（`uint32_t`，偏移 0）是窗口定位**唯一**需要的字段；packed `win_last_docid_` 即把这 4B 抽出连续存放，复用 `sb_last_docid_` 的设计思路。**`WindowMeta` 布局不变。** - -## 3. 变更设计 - -### 3.1 单调双指针游标（替代 per-candidate `locate_window`） - -候选升序 + 窗口 `last_docid` 非降（构建期不变量见 §3.4），窗口在 docid 空间上**连续不重叠地分区**（窗口 w 覆盖 `(win_base(w), last_docid(w)]`，`win_base(w)=last_docid(w-1)`）。因此一个**只前进**的窗口游标即可复现 `locate_window` 的"首个 `last_docid ≥ d` 的窗口"。为同时兼顾**稀疏候选/超多窗口**的情形（纯线性游标在 C≪N 时退化为 O(N)，可能劣于旧的二分），保留 super-block 级单调游标做**边界跳跃**，得到严格 O(C + N)、且不劣于旧实现： - -```cpp -// frq_prelude.cpp —— 隔离可测的纯函数核心（对数组操作，无 FrqPreludeReader/IO） -void select_covering_windows_cursor(const uint32_t* win_last_docid, uint32_t n_windows, - const uint64_t* sb_last_docid, uint32_t n_super, - uint32_t group_size, - const std::vector& candidates, - std::vector* windows) { - windows->clear(); - if (n_windows == 0) return; // empty-windows guard (locate_window:450) - uint32_t sb = 0; // monotonic super-block cursor - uint32_t w = 0; // monotonic window cursor - uint32_t last_emitted = UINT32_MAX; - for (uint32_t d : candidates) { - // Level-1: first super-block whose absolute last_docid >= d (monotone, total <= n_super). - while (sb < n_super && static_cast(d) > sb_last_docid[sb]) ++sb; - if (sb == n_super) break; // d past term's last docid -> all remaining miss - // Boundary jump: never scan windows below the current super-block's first window. - if (w < sb * group_size) w = sb * group_size; - // Level-2: first window with last_docid >= d (monotone forward, total advances <= N). - while (w < n_windows) { - ++g_window_probes; // op-count seam (window last_docid comparison) - if (d <= win_last_docid[w]) break; - ++w; - } - if (w == n_windows) break; // defensive; invariants guarantee a hit here - if (w != last_emitted) { windows->push_back(w); last_emitted = w; } - } -} -``` - -**复杂度**：窗口前进 `++w` 总数 ≤ N（游标全程 0→n 单向），每候选至多 1 次"命中比较"（≤ C），故 **窗口比较 `g_window_probes` ≤ C + N**；super-block 前进 ≤ n_super、每候选 1 次停查 ≤ C，均为低阶项。**与 G 无关**（旧实现的 O(C·G) 重扫被消除）。 - -**边界跳跃为何正确**：`sb` 是首个 `sb_last_docid[sb] ≥ d` 的 super-block，则所有 `< sb` 的 super-block 内窗口 `last_docid ≤ sb_last_docid[sb-1] < d`，对当前及更大候选都不可能覆盖；把 `w` 跳到 `sb*group_size` 只跳过这些不可能命中的窗口，不漏不重。 - -### 3.2 与旧实现逐元素等价的论证（不变量驱动） - -- `locate_window(d)` 返回"首个 `last_docid ≥ d` 的窗口 w"（`frq_prelude.cpp:461`）；游标 level-2 在 `d ≤ win_last_docid[w]` 处停（`++w` 仅越过 `last_docid < d` 的窗口）→ 停位 == `locate_window(d)`。 -- **miss 处理**：`locate_window` 在 `docid > windows_.back().last_docid` 时 `*found=false`（`:451`）；游标在 `sb==n_super`（即 `d > sb_last_docid.back() == windows_.back().last_docid`）或 `w==n_windows` 时 `break`，对当前及后续候选**均不再 emit**——与旧 `if(!found) continue` 的输出**逐元素相等**（验证器明确："break early -- matching locate_window line 451"）。 -- **去重/顺序**：`if (w != last_emitted)` 与旧 `if (w != last)` 一致；游标单调 → 升序。 -- 即便出现 `last_docid` 相等的退化窗口（实际不会：`first_docid_in_window` 在 `first > last_docid` 时报 Corruption，`docid_conjunction.cpp:109`，故每窗 ≥1 doc、`last_docid` 严格递增），游标停在"首个 `last_docid ≥ d`"仍与 `locate_window` 的 `<=` 语义一致。 - -### 3.3 packed `win_last_docid_`（可选 cache-locality polish）+ 成员桥接 - -在 `open()` 内随 `sb_last_docid_` 一并构建（in-memory only，**零在盘变更**）： - -```cpp -// frq_prelude.cpp FrqPreludeReader::open，紧随 :429-432 sb_last_docid_ 构建之后 -out->win_last_docid_.clear(); -out->win_last_docid_.reserve(out->windows_.size()); -for (const WindowMeta& m : out->windows_) out->win_last_docid_.push_back(m.last_docid); -``` - -```cpp -// frq_prelude.h —— inline 零拷贝标量访问器（DCHECK 边界，release 零开销） -uint32_t window_last_docid(uint32_t w) const { DCHECK_LT(w, win_last_docid_.size()); return win_last_docid_[w]; } - -// 成员桥接：把私有目录数组喂给纯函数核心 -void FrqPreludeReader::select_covering_windows(const std::vector& candidates, - std::vector* windows) const { - select_covering_windows_cursor(win_last_docid_.data(), - static_cast(win_last_docid_.size()), - sb_last_docid_.data(), - static_cast(sb_last_docid_.size()), - group_size_, candidates, windows); -} -``` - -游标扫描只触碰 4B/窗口的连续 `win_last_docid_`，不再触碰 ~104–112B 的 `WindowMeta`。验证器口径：这是**次要 polish**（组 L1 常驻，cache 收益小，dominant win 来自游标消除重扫）。即便不加 packed 数组，游标改用 `windows_[w].last_docid`（偏移 0）也能拿到绝大部分收益；本设计采用 packed 数组为更干净的扫描局部性，且其正确性由"位级等于 `windows_[w].last_docid`"覆盖（§6 FV-10）。 - -### 3.4 计数 seam（确定性性能断言） - -```cpp -// frq_prelude.cpp 匿名命名空间 -namespace { uint64_t g_window_probes = 0; } -namespace testing { -uint64_t window_probe_count() { return g_window_probes; } // 唯一读出点 -void reset_window_probe_count() { g_window_probes = 0; } // 测试间 reset -} // namespace testing -``` - -唯一计数语义 = **窗口 `last_docid` 比较次数**，在**两条路径的同一比较点**自增：游标 level-2 的 `++g_window_probes`（§3.1）与 `locate_window` level-2 扫描（`frq_prelude.cpp:460-466`）的循环体首。如此可 apples-to-apples 对比：旧路径随 G 增长（dense 时 ≈ C·扫描深度），新游标 ≤ C + N 且与 G 无关。 - -### 3.5 FORMAT-COMPATIBILITY（格式影响） - -**reader-only，零在盘字节变更**（非 T18）。`win_last_docid_` 纯 in-memory，于 `open()` 由已解码的 `windows_` 派生，不进入序列化/反序列化；`WindowMeta`/prelude 在盘布局、CRC、版本号均不变。已写盘索引无需重写、完全兼容。 - -### 3.6 CONCURRENCY（并发与锁影响） - -**无新增共享可变状态，无锁、无锁内 IO 风险。** `win_last_docid_` 在 `open()` 中完全物化、之后不可变（与 `windows_`/`sb_last_docid_` 同生命周期，`frq_prelude.h:175` 契约）；`FrqPreludeReader` 随共享 `LogicalIndexReader` 被并发查询共享，但游标用到的 `sb`/`w`/`last_emitted` 均为 `select_covering_windows_cursor` 的**栈局部变量**，目录数组为只读 const 引用。符合规范 §5"共享 `LogicalIndexReader` 现为 const 无锁只读"。`g_window_probes` 为 **test-only** 计数（生产路径不读、测试单线程 reset/读），不引入并发语义。**无需 TSAN 门禁。** - -## 4. 依赖 - -- `depends_on`：**无硬依赖**。本任务自包含（`frq_prelude.{h,cpp}` + `docid_conjunction.cpp` 调用点改一行）。 -- **T20（FrqPreludeReader WindowMeta 零拷贝引用访问器 `window_at`）**：互补且独立。T20 给"读整 `WindowMeta`"的循环去拷贝；T10 给"窗口定位"加 4B 标量 packed 数组 + 游标。二者命名/职责不冲突，可任意先后合入；若 T20 已落，`collect_windowed_docids_only` 仍按各自访问器走，互不影响。 -- **T23（prelude 按 super-block 惰性解码）**：**软关系，非硬依赖**。T23 若让 `windows_` 惰性化，则 T10 在 `open()` 中**急切**构建全量 `win_last_docid_` 会与惰性目标相抵。集成顺序上二选一：(a) 合入 T23 后令 `win_last_docid_` 同样按 super-block 惰性填充；或 (b) 游标降级为读已（惰性）解码的 `windows_[w].last_docid`，放弃 packed polish。两任务分属不同 batch（T10∈b2，T23∈b5），当前无强耦合，集成时按上述策略消解即可。 -- **提供（shared-infra）**：`doris::snii::format::testing::window_probe_count()` 作为"窗口定位算法"的确定性 op-count 样板；`select_covering_windows_cursor(...)` 作为可被其他归并式选择复用的纯函数核心。 -

-**Step 1（RED — 等价性失败保护）**：写 `EquivalenceMatchesOracleOnRandomAscendingSets`：固定 RNG 生成多组（N、G、严格递增 `win_last_docid`、派生 `sb_last_docid`、升序候选），断言 `select_covering_windows_cursor(...) == oracle_select(...)`（`EXPECT_EQ` 全量）。函数尚未实现 → 编译/链接失败 → RED。 - -**Step 2（GREEN — 实现游标核心）**：实现 §3.1 `select_covering_windows_cursor` + §3.4 计数 seam（先不接 `FrqPreludeReader`）。Step1 转 GREEN。 - -**Step 3（RED — 探测复杂度不变量）**：写 `CursorProbeCountStaysLinearInCandidatesPlusWindows`：`reset_window_probe_count()` → 游标 → `EXPECT_LE(window_probe_count(), candidates.size() + n_windows)`，覆盖 dense（C≈64·W）与 sparse（C≪N）两形状。当前若误用某非游标实现会超界；用此锁定 O(C+N)。再写 `LegacyLocateWindowProbeGrowsWithGroupSize`：用真实 `make_test_prelude(last_docids, G=8/64)`（经 `build_frq_prelude`+`open`），对同一窗口集分别跑 per-candidate `locate_window` 计数，断言 `probes_old(G=64) > probes_old(G=8)` 且 `> C+N`；而游标在 G=8/64 上 `window_probe_count()` **相等且 ≤ C+N**。（旧 `locate_window` 尚未插 seam → RED。） - -**Step 4（GREEN — 接通 reader 成员 + 计数 seam + 改调用点）**：在 `open()` 构建 `win_last_docid_`（§3.3）；加 `window_last_docid` 访问器、`FrqPreludeReader::select_covering_windows` 成员；在 `locate_window` level-2 循环插 `++g_window_probes`；删除 `docid_conjunction.cpp:497-514` 匿名函数、把 `:691` 改为成员调用。Step3 转 GREEN；Step0 的 `phrase_query` golden 结果集逐元素不变。 - -**Step 5（REFACTOR）**：清理；跑 `be-code-style`。复跑既有 `SniiPhraseQueryTest.*`、`SniiSegmentReaderTest.*`、`SniiTermQueryTest.*` 全 GREEN，证明窗口读路径无回归。`locate_window` 保留为公开 API + 测试 oracle（公开方法，无 `-Wunused`）。 - -## 6. 功能验证 -

-**Step 3（RED — 消除第三遍 / 减分配）**：写 `WidthEvalsEqualsNPerRun`（op-count）：`reset_pfor_width_evals()` → `pfor_encode(run of n)` → `EXPECT_EQ(pfor_width_evals(), n)`。当前（仍三遍）会得到 `>n` → RED。 - -**Step 4（GREEN — pfor_encode 复用 widths + bitpack_masked）**：实现 §3.3。Step3 转 GREEN；Step0 golden 再次逐字节相等（异常表/bitpack 字节不变）。 -

stats_.sum_total_term_freq += fs.total_freq; // 复用，不再 SumOf - ... // block open 逻辑不变 - SNII_RETURN_IF_ERROR(build_entry(tp, st->frq_base, st->prx_base, fs, &e)); - ... -} -``` -注意：必须在 `validate_term` **之前**算 `fs`（验证器要求：要么 validate 收预算值，要么先 fused 再 validate）。这里二者皆做：fused 先行，validate 收 total_freq。 - -### 3.3 validate_term / build_entry 签名变更 -- `Status validate_term(const TermPostings& tp, uint64_t total_freq) const;` - - 删除内部 `:358-359` 求和循环；`has_prx_` 分支直接 `if (total_freq != have) return InvalidArgument(...)`。 - - **保留** `freqs.size()==docids.size()` 校验（`:354-356`）与严格升序 docid 校验（`:368-372`）——这两者不涉及 freqs 求和，原样保留。 -- `Status build_entry(TermPostings& tp, uint64_t frq_base, uint64_t prx_base, const FreqStats& fs, DictEntry* e);` - - `e->ttf_delta = fs.total_freq;`（替换 `:481`） - - `e->max_freq = fs.max_freq;`（替换 `:482`） - - 其余分流 windowed/slim 不变。 - -> `FreqStats` 定义需对 .h 可见（build_entry 签名引用）。方案：在 `logical_index_writer.h` 的 `doris::snii::writer` 命名空间内定义轻量 `struct FreqStats { uint64_t total_freq=0; uint32_t max_freq=0; };`，.cpp 的 `fuse_freq_stats` 返回它。 - -### 3.4 op-count 测试 seam -仿 spec §4 的 `dict_decode_counter()` 模式，新增 task-local seam（声明于 .h，定义于 .cpp）： -```cpp -namespace doris::snii::writer::testing { -void note_term_freq_scan(); // 每次 term 级 fused 扫描 +1 -uint64_t term_freq_scans(); // 自上次 reset 起的累计值 -void reset_term_freq_scans(); // 测试间清零 -} -``` -定义用函数内静态 `std::atomic`（与 build 单线程路径一致；atomic 仅为 TSAN 友好）。生产路径除一次 relaxed 自增外零开销。 - -### 3.5 结论（强制声明） -- **FORMAT-COMPATIBILITY**：reader/writer-only，**零在盘变更**。`ttf_delta`/`max_freq`/`sum_total_term_freq` 值逐字节不变，只是计算次数从 3-4 变 1。非 T18，不触在盘字节。 -- **CONCURRENCY**：见 §4。本任务只触及**单线程 writer 构建路径**，不触及共享 `LogicalIndexReader` 任何可变状态。无共享可变状态，N/A。 -

-**Step 0（RED — op-count，先暴露冗余）** -1. 在 .h 声明 `testing::note_term_freq_scan/term_freq_scans/reset_term_freq_scans`，.cpp 实现计数器。**先**在**现有 4 个 term 级扫描点**各插一次 `note_term_freq_scan()`：`validate_term` 的 has_prx 求和、`process_term` 的 `SumOf`(`:540`)、`build_entry` 的 `SumOf`(`:481`) 与 `MaxOf`(`:482`)。 -2. 写 `TEST(SniiWriterTest, ProcessTermScansFreqsOncePerTerm)`：build 一个含已知 term 数 N 的 index，`EXPECT_EQ(term_freq_scans(), N)`。 - **失败原因**：当前计数 ≈ 3N（无 prx）或最多 4N（has_prx），≠ N。 - -**Step 1（GREEN — 融合）** -3. 引入 `FreqStats` + `fuse_freq_stats`（含**唯一**一次 `note_term_freq_scan()`），改 `process_term`/`validate_term`/`build_entry` 签名与调用（§3.2-3.3），移除旧 4 点的 `SumOf`/`MaxOf` 及其计数。 - `term_freq_scans()` 回到 N → 测试转 GREEN。 - -**Step 2（GREEN — 值等价回归，防止 CSE 改变语义）** -4. 写 `TEST(SniiWriterTest, FusedFreqStatsPreserveTtfMaxAndSum)`：build_reader 同构数据，对每个 term `lookup()` 读回 `entry.ttf_delta`/`entry.max_freq`，与测试内**独立参考** `ref_sum=Σfreqs`、`ref_max=max(freqs)` 全量 `EXPECT_EQ`；并 `EXPECT_EQ(reader.stats().sum_total_term_freq, Σ_all_terms ref_sum)`。该用例改前改后都必须 PASS（守护等价）。 - -**Step 3（GREEN — 纯函数单测，边界）** -5. 写 `TEST(SniiWriterTest, FuseFreqStatsMatchesReferenceOnEdgeInputs)`：对 `fuse_freq_stats` 直接喂边界输入（空、单元素、全相等、含 0、`UINT32_MAX`、大数组随机），断言 `{total,max}` 与 naive `SumOf`/`MaxOf` 逐项相等。（需将 `fuse_freq_stats` 通过 testing seam 暴露，或在测试 TU 内以等价 helper 对拍——优先暴露真实 helper 以测真实代码。） - -**Step 4（REFACTOR）** -6. 清理：确认 term 级路径不再调用 `SumOf`/`MaxOf` on `tp.freqs`；若 `SumOf` 已无任何调用方则删除（`MaxOf` 仍被 window 路径用，保留）。`be-code-style` 跑 clang-format。 - -每批自闭环：业务代码 + UT 同批交付。 - -## 7. 功能验证 - -gtest target：`doris_be_test`，文件 `be/test/storage/index/snii_writer_test.cpp`。运行：`./run-be-ut.sh --run --filter='SniiWriterTest.*'`。 -

-**Step 1（RED — 小窗跳过）**：写 `TEST(SniiPrxPodCounterTest, SmallWindowSkipsRawPlaintextBuild)`：构造一个明文 <512B 的小窗（如 3 doc、每 doc 2 个位置），`reset_prx_raw_build_count()` 后调用 `build_prx_window_flat(..., kAutoZstd, &sink)`，断言 `prx_raw_build_count() == 0`。当前代码恒物化 → 实际为 1 → **FAIL**。 - -**Step 2（GREEN）**：实现 §3 的 `compute_flat_deltas` / `encode_pfor_payload_from_deltas` / `exact_plain_payload_size` / `encode_payload_from_deltas`，改写 `build_prx_window_flat` auto 分支：仅当 `plain_size >= kAutoZstdMinBytes` 才物化明文并 `note_prx_raw_build()`。小窗计数归 0 → GREEN。补 `TEST(SniiPrxPodCounterTest, LargeWindowStillBuildsRawPlaintextOnce)`（明文 >=512B → 计数 ==1）。 - -**Step 3（RED — 字节一致 / 边界 codec）**：写 `TEST(SniiPrxPodTest, FlatAutoProducesByteIdenticalOutputAcrossSizes)`（flat 路径 vs per-doc 路径逐字节相等，含跨 512 的大窗）与 `TEST(SniiPrxPodTest, AutoCodecChoiceMatchesBruteForceAtThreshold)`（独立用 `pfor_frame_size`/`zstd_frame_size` 重算，断言发射的 codec 字节一致）。在仅改了 flat、未改 vector 路径的中间态，大窗用例会暴露不一致 → FAIL。 - -**Step 4（GREEN）**：把 vector 版 `build_prx_window` auto 分支也改为「扁平→`compute_flat_deltas`→同序列」，两路恢复字节一致 → GREEN。 - -**Step 5（REFACTOR）**：让旧 `encode_pfor_payload_flat`/`encode_payload_flat` 复用 `compute_flat_deltas`（或保留供 forced 分支调用，避免改 forced 路径行为）；清理重复 delta 推导；`be-code-style` 跑 clang-format。所有测试保持 GREEN，不改测试。 -

-- 堆排序比较器 `HeapGreater::operator()` 随机索引 `(*vocab)[a.term_id]` / `(*vocab)[b.term_id]` 并逐字节比较（`spill_run_codec.cpp:350-355`）。 -- 每个 term 的 gather 循环 `vocab[heap.top().term_id] == merged.term`（`spill_run_codec.cpp:459`）。 - -由于 vocab 在所有 run 间**共享且稠密**（同一 term 在每个 run 里 term_id 相同），这些比较本可纯整数化。该路径在生产真实触发：accumulator 超过 gate-2 cap 即 spill 成 K 个 run 并经 `merge_runs`→`MergeRuns`（`spimi_term_buffer.cpp:530`）。堆做 O(N log K) 次比较（N = 跨 run 的 term 条目总数，大段可达数百万；K 通常个位到低两位数），每次比较随机索引 `std::vector`（32 B/slot）并 length+memcmp。 - -**已有的复用基础**：`string_rank_`（term-id → 全词典字典序 rank，4 B/id 稠密数组）已经在 spill 路径上被构建——每次 spill 经 `drain_to_writer`→`sorted_ids()`→`ensure_string_rank()`（`spimi_term_buffer.cpp:402-424`），声明为 `mutable`（`spimi_term_buffer.h:355-359`）。作者已在 `sorted_ids()`（`spimi_term_buffer.cpp:415-424`）用同一技术把每次 spill 的 id 排序从 strcmp 改成整数 rank 比较。 - -**预期收益**：把归并内层循环里所有「随机 vocab 字符串访问 + 字节比较」改为「稠密 4 B 整数数组的整数比较」（约 8x 更密、cache 友好、整数比较代替 length+memcmp）。验证器评估为**真实但低量级**的微优化：归并主成本是 run IO / PFOR 解码 / Concat 的 positions memcpy（最宽 term 的数组达数十 MiB），term-id 排序不是主导。修复几乎零成本、已在同文件兄弟代码中确立，因此值得做。 -

-经全仓 grep 确认 `MergeRuns` **仅此一个调用点**（`spimi_term_buffer.cpp:530`），无外部测试直接调用。 - -### 3. 变更设计 - -**核心思路**：把已存在的 `string_rank_`（term-id → 字典序 rank）注入 `MergeRuns`，堆按 `rank[term_id]` 排序（uint32 整数比较），gather 按 `heap.top().term_id == id` 整数相等聚合，完全不在内层循环访问 vocab 字符串。`merged.term` 仍每个 term 经 `vocab[id]` 解析一次（保持不变）。 - -**3.1 新签名（`spill_run_codec.h` / `.cpp`）** -```cpp -Status MergeRuns(const std::vector& run_paths, - const std::vector& vocab, - const std::vector& string_rank, // 新增：term-id -> 字典序 rank - bool has_positions, - const std::function& fn, - bool allow_stream_positions = true); -``` -保留 `vocab` 参数（仍需 `vocab[id]` 解析 merged.term）；新增 `string_rank` 借用引用（const ref，调用方在 finalize 后传入，构建期单线程无并发）。 - -**3.2 比较器改为整数 rank** -```cpp -struct HeapGreater { - const std::vector* rank; - bool operator()(const HeapItem& a, const HeapItem& b) const { - const uint32_t ra = (*rank)[a.term_id]; - const uint32_t rb = (*rank)[b.term_id]; - if (ra != rb) return ra > rb; // 字典序：rank 小者优先（min-heap） - return a.run > b.run; // 同 term 跨 run：run 序 tie-break（docid 升序） - } -}; -``` -正确性依据（验证器确认）：vocab 稠密、每个 id 映射**不同**字符串（`spimi_term_buffer.h:141-143` 文档化），所以 rank 是字符串字典序的双射 → 按 rank 排序复现完全一致的字典序；不同 id rank 不同，run 序 tie-break 保持。 - -**3.3 gather 改为整数 id 相等** -```cpp -const uint32_t id = heap.top().term_id; -TermPostings merged; -merged.term = vocab[id]; // 仍每 term 解析一次字符串 -... -while (!heap.empty() && heap.top().term_id == id) { // 整数相等，零 vocab 访问 - ... -} -``` -稠密 vocab 下「相同字符串 ⟺ 相同 id」，验证器明确指出原 :453/:459 的「重复字符串」防御性 hedge 在 dense-vocab 契约下不必要，可安全去除。 - -**3.4 入口防御** -```cpp -if (string_rank.size() != vocab.size()) - return Status::Internal("MergeRuns: string_rank/vocab size mismatch"); -``` -保证比较器索引 `rank[term_id]` 在 `current_id() < vocab.size()` 守卫（:438/:587 保留）下越界安全。 - -**3.5 调用方（`spimi_term_buffer.cpp:530`）** -```cpp -ensure_string_rank(); // 显式构建（验证器 caveat (a)：若本次 merge 之前无 spill 触发 sorted_ids，避免 rank 陈旧/空） -Status s = MergeRuns(run_paths_, vocab(), string_rank_, has_positions_, fn, allow_stream_positions); -``` -`merge_runs` 是非 const、`ensure_string_rank()` 是 const 且 `string_rank_` 为 mutable，可在此调用；rank 在传入前已最终化，按 const ref 借用（验证器 caveat (b)）。注：实践中 merge_runs 仅在已发生 spill（`run_paths_` 非空）时进入，而每次 spill 都已调过 `ensure_string_rank()`，显式再调一次幂等（:404 已有 size 相等即返回的短路）。 - -**3.6 注释更新**：同步修订 `HeapGreater` 注释（:340-343）、`MergeRuns` 头注释（`spill_run_codec.h:160-176` "orders by VOCAB STRING" → "orders by the precomputed integer string-rank; merged.term resolved from vocab once per term"）、gather 注释（:452-456 去掉「duplicate string still groups」hedge）。 - -**格式影响（FORMAT-COMPATIBILITY）**：reader/writer-only，零在盘变更。run 是私有临时文件，wire 格式（term_id varint + raw u32 blocks）完全不变；归并发射顺序与 postings 逐字节不变（rank 是字典序双射）。产出的 .idx 字节级一致。本任务 `On-disk format change=false` 成立。 - -**并发与锁结论（CONCURRENCY）**：N/A，无共享可变状态。SPIMI 构建是**单线程**（finding 与 CONCURRENCY.md 一致）；`MergeRuns` 与 `SpimiTermBuffer` 不在查询读路径上、不触及共享 `LogicalIndexReader`。`string_rank_` 虽为 mutable/lazy，但仅构建期单线程访问；新增参数按 const ref 在最终化后传入，无数据竞争。不引入任何锁，不触碰 NO-IO-UNDER-LOCK 红线。 -

-- `report_arena_delta()`（`spimi_term_buffer.cpp:83-90`）计算 `now = resident_bytes()`，然后**无条件**调用 `mem_reporter_->report(now - reported_resident_)`。 -- `MemoryReporter::report()`（`memory_reporter.h:31-34`）始终执行 `current_.fetch_add(delta, relaxed)`——x86 上即 `lock xadd`（约 10-20 cycle 的带 full barrier 锁前缀指令），**即使 delta==0**。 -- `resident_bytes() = pool_.arena_bytes() + slot_of_.capacity()*4`（`spimi_term_buffer.cpp:96-103`）；`arena_bytes() = blocks<<15`（块粒度，约每 32 KiB 才变一次），借用 vocab 模式下 `slot_of_` 容量在构造时固定（`spimi_term_buffer.cpp:56` 用 `assign(vocab_size,0)`，此后只 `[]` 写入，capacity 不再增长）。**绝大多数 token 的 delta 为 0**，却仍付出一次锁前缀 `fetch_add(0)`。 - -**期望收益**：消除热路径上几乎全部 per-token 原子 RMW（arena 约每 32 KiB 才增长一次），把 `report()` 调用从 O(token 数) 降到 O(arena 增长事件数)。验证器修正：墙钟收益是真实但很小的（远小于 build CPU 1%），且 Doris 下 `consume_release==null`，被省掉的仅是一次原子加；因此本任务的价值定位为"消除热路径上确定可计数的多余原子写"，用**确定性 op-count** 验证，而非墙钟。 - -**验证器关键纠正（必须遵守）**： -- 修复**只**做"delta==0 时跳过 `report()`"这一半。`report_arena_delta()` 内 early-return 即可，字节等价、线程安全、零在盘影响。 -- **禁止**修复的第二半（把 `over_cap()` 用本 buffer 的 arena delta 来 gate 或缓存其结果）。`over_cap()` 读的是 **writer 级 UNIFIED 总量**，与 dict buffer 共享同一个 `mem_reporter`（`logical_index_writer.cpp:351` 用同一 reporter 构造 `dict_buf_`；`memory_reporter.h:38-42` 注明 unified total = arena + slot index + dict）。dict 侧增长可在本 buffer delta==0 时把总量推过 cap；gate 掉就会漏掉 spill 触发。且 `over_cap()` 只是 relaxed load+compare（无锁前缀），便宜，无需 gate。**每个 token 仍无条件调用 `over_cap()`**。 - -## 2. 影响的文件/函数 - -**唯一实现改动**：`be/src/storage/index/snii/writer/spimi_term_buffer.cpp` - -当前签名/实现（`:83-90`）： -```cpp -void SpimiTermBuffer::report_arena_delta() { - if (mem_reporter_ == nullptr) return; - const int64_t now = static_cast(resident_bytes()); - mem_reporter_->report(now - reported_resident_); // 无条件 fetch_add(可能为 0) - reported_resident_ = now; -} -``` - -调用点（均经此函数，无需逐点改）：`:59`（ctor 报告 slot_of 初值）、`:180`（accumulate 热路径）、`:458`（drain_sorted 末尾负值）、`:480`（drain_to_writer spill 后负值）、`:529`（merge_runs 释放 slot_of 负值）。后三处报告的都是**非零负 delta**（释放），early-return 不影响；`:180` 是受益点。 - -**不改**：`memory_reporter.h`（`report()`/`over_cap()` 语义不动）、`accumulate()` 内 `over_cap` 分支（`:187-189`，保持每 token 无条件求值）、`spimi_term_buffer.h`（无签名变更）。 - -## 3. 变更设计 - -**改动（极小）**：在 `report_arena_delta()` 计算 `now` 后，若 `now == reported_resident_`（即 delta==0）直接返回，跳过 `report()` 与 `reported_resident_` 赋值： - -```cpp -void SpimiTermBuffer::report_arena_delta() { - if (mem_reporter_ == nullptr) return; - const int64_t now = static_cast(resident_bytes()); - if (now == reported_resident_) return; // skip the per-token zero-delta locked fetch_add - mem_reporter_->report(now - reported_resident_); - reported_resident_ = now; -} -``` - -**语义等价性论证**：被跳过的调用 delta 恒为 0。`current_.fetch_add(0)` 对原子值无效果；`consume_release(0)`（Doris 下为 null）若存在也是镜像 0；delta==0 时 `now==reported_resident_`，不更新 `reported_resident_` 仍保持其等于 `now`。因此 `current_bytes()` 在任意时刻、`over_cap()` 的每次求值结果、gate-2 spill 触发时机，改前改后**逐位相同**。`accumulate()` 的 `over_cap` 检查仍在 `report_arena_delta()` 之后无条件执行（`:187-191`），与设计一致。 - -**FORMAT-COMPATIBILITY**：reader/writer-only，零在盘变更（仅省略一次内存原子写，不触及任何字节流）。 - -**CONCURRENCY**：`SpimiTermBuffer` 是 **per-segment writer 的单线程构建对象**（一个 segment 倒排索引一个 writer），不在 `LogicalIndexReader` 共享读路径上，无共享可变状态被并发访问。`mem_reporter_->current_` 本身是 atomic（为兼容 Doris 端可能的并发镜像而设），但 T17 不增加任何新的共享可变状态、不引入锁、不在锁内做 IO/解压。结论：**无并发回归风险**（详见 §9 与 CONCURRENCY.md：本任务不触及 H1/H2 涉及的共享 reader 缓存与 reader-open 路径）。 -

-**reader 推导算法**（在 `decode_all_blocks` 中维护三个 u64 running 累加器，跨 super-block 链接，与 `prev_last` 同生命周期）： -- `decode_window_row` 读 `dd_disk_len` 后：`m->dd_off = *dd_run; *dd_run += m->dd_disk_len;`；`m->dd_uncomp_len = m->dd_zstd ? <读VInt> : m->dd_disk_len;`。 -- has_freq 时对 `freq_off`/`freq_uncomp_len` 同理（`*freq_run`）。 -- has_prx 时：`m->prx_off = *prx_run; *prx_run += m->prx_len;`。 -- 累加前用 `checked_add_u64` 防溢出（沿用现有 helper），失败返回 `Corruption`。 - -**FORMAT-COMPATIBILITY 结论**：**有在盘字节变更**。`format_constants.h:18-24` 明确这是 from-scratch、pre-launch 格式（无已落盘索引），`kMetaFormatVersion=1` 注释要求"pre-launch 变更直接折叠进 v1"。本计划**折叠进 v1**：新编码即唯一编码，writer/reader 对称，无旧格式双路径，`kMetaFormatVersion` 保持 1（prelude 不受 meta version 管辖，是 `.frq` posting 内部格式）。**回退门控**：若合入前发生 launch（出现 `lifecycle: launched` 索引），改用 prelude header flags 字节新增 `kSlimRows`（`1u<<2`，现仅用 kHasFreq/kHasPrx）作门控位，reader 按位选解码路径——本计划保留该 flags 字节扩展点，但默认不启用双路径。 - -**CONCURRENCY 结论**：**N/A，无共享可变状态**。`encode_window_row`/`decode_*` 是纯函数，只操作 caller 提供的 `ByteSink`/`ByteSource`/局部 `WindowMeta`/`std::vector`。`FrqPreludeReader` 在调用方是 query-local（`scoring_query.cpp:169/331`、`docid_conjunction.cpp:817`、`windowed_posting.cpp` 栈上），非共享 reader 的 per-reader 可变状态。不触及 `LogicalIndexReader` 的 const 只读路径，不引入任何锁。 - -**鲁棒性补偿（F11 验证器纠正 #2/#3）**：删除独立存储的 off 后，`validate_region_layout` 的 off 交叉校验失效（推导值恒等）。保留并依赖：(a) `windowed_posting.cpp` 中 `CarveRegionSlices`/`windowed_window_range` 的 `InBounds(m.dd_off, m.dd_disk_len, dd_block_len)`、`InBounds(m.freq_off, ..., freq_block_len)`（`:79,83,132,137`）；(b) prx 的 `InBounds(meta.prx_off, meta.prx_len, entry.prx_len)`（`:148,244`）；(c) `decode_all_blocks` 的窗口区 `block_off+block_len<=window_region.size()` 检查（`:352`）；(d) 推导累加的 `checked_add_u64` 溢出保护。raw 区 `uncomp_len==disk_len` 由 `open_region`（`frq_pod.cpp:112`）继续 enforce。 -

-**关键正确性点（验证器纠正）**： -- crc 的 `view()` 必须在写完 payload **之后、写 crc 之前**取——此刻 `buf_` 连续、无后续插入，`subslice(start, framed_len)` 指向的内存有效，无 realloc/aliasing 隐患。 -- crc 覆盖的字节范围 = `[codec/type][varint len][payload]`，与 reader（`read_framed` `prx_pod.cpp:612-638` / `SectionFramer::read`）重新推导的 `slice_from(start, framed_len)` 完全一致，故 CRC 值不变。 -- `put_fixed32` 写的是 4 字节小端（`byte_sink.cpp:11-13`），与原 `sink->put_fixed32(crc32c(framed.view()))` 字节一致。 -

meta->crc = crc32c(plain); // raw 上盘字节 == plain，故 CRC 不变 - out->put_bytes(plain); - return Status::OK(); -} -``` -**正确性点**：reader 侧 `open_region`（`frq_pod.cpp:97-121`）对 raw 区强校验 `uncomp_len == disk_len` 且 `crc32c(disk) == meta.crc`；因 raw 上盘字节逐字节等于 `plain`，`disk_len = plain.size()`、`crc = crc32c(plain)` 保持不变量成立。`plain`（来自 `ByteSink::view()`，连续）满足 `crc32c(Slice)`/`put_bytes(Slice)`。 - -### 3.3 bitpack 去逐字节 push_back（F32 子项） - -`bitpack` 在循环前按精确字节数预留，消除 realloc 抖动（验证器纠正：`reserve` 取**绝对容量 size()+needed**，否则缓冲增长后再 reserve 同值即 no-op，因为 `encode_pfor_runs` 复用同一 `out` 跨多个 run）。两个 run 编码器（`prx_pod.cpp:104` / `frq_pod.cpp:36`）run 长度恒 `<= kFrqBaseUnit=256`，w<=32 → packed `<= (32*256+7)/8 = 1024` 字节，故可用栈缓冲一次 `put_bytes`： -```cpp -void bitpack(const uint32_t* v, size_t n, uint8_t w, ByteSink* out) { - if (w == 0) return; - const size_t packed = (static_cast(w) * n + 7) / 8; - out->reserve(packed); // 新增 ByteSink::reserve(additional) - // 仍逐字节填，但已无 realloc；保留原 acc/filled 位拼装逻辑，字节完全一致 - ... -} -``` -为兼容未来可能的大 n 直接调用，采用 `reserve(packed)`（通用、简单、必然位级一致）作为主方案；栈缓冲 + 单次 `put_bytes` 作为可选优化（需 `packed <= 栈上限` 的运行时回退）。本计划落地 `reserve` 方案。`ByteSink::reserve`： -```cpp -void reserve(size_t additional) { buf_.reserve(buf_.size() + additional); } -``` - -### FORMAT-COMPATIBILITY 结论 -**reader/writer-only，零在盘变更**。三处 framing、emit_region raw、bitpack 均产出与改前**逐字节相同**的 on-disk 字节与 CRC（§3 各点已逐一论证 crc 覆盖范围/长度不变）。 - -### CONCURRENCY 结论 -**N/A，无共享可变状态**。全部改动位于单线程 build 路径；`ByteSink` 是函数局部对象，`emit_region`/`bitpack` 仅操作入参 `Slice` 与调用方私有 sink。不触及共享 `LogicalIndexReader`、不在任何锁临界区内、不涉及 IO/解压（NO-IO-UNDER-LOCK 红线无关）。 -

- `FrqPreludeReader::window(uint32_t, WindowMeta*) const` / `locate_window(...) const`：改为按需触发目标 super-block 的惰性解码。 - - 新增 `private` 帮助函数：`ensure_super_block_decoded(size_t sb) const`（解码并缓存第 sb 个 super-block 的 window 行；`mutable`）。 - - 复用现有 `decode_one_block`/`decode_window_row`/`SbDirRow`/`Header`（保持解码与校验逻辑一致）。 - -不改动的调用方（签名/语义不变，惰性对其透明）： -- `docid_posting_reader.cpp:164-181`（open 后立即用 `dd_block_len()` 校验前缀长度，再逐 window 全量遍历）。 -- `windowed_posting.cpp:48-64`（`ResolveBlocks` 用 `dd_block_len()`/`freq_block_len()`）、:121-139（`windowed_window_range` 用 `window(w)`）、:238-241。 -- `docid_conjunction.cpp:497-514, 631, 817`、`scoring_query.cpp:92-107, 357, 428-430`。 - -当前关键签名（不变）： -- `static Status FrqPreludeReader::open(Slice prelude, FrqPreludeReader* out);` -- `Status window(uint32_t w, WindowMeta* out) const;` -- `Status locate_window(uint32_t docid, bool* found, uint32_t* w) const;` -- `uint64_t dd_block_len() const; uint64_t freq_block_len() const; uint32_t n_windows() const; uint32_t n_super_blocks() const;` - -## 3. 变更设计 - -### 数据结构（FrqPreludeReader 私有成员） -保留：`has_freq_/has_prx_/group_size_/n_super_/dd_block_len_/freq_block_len_/sb_last_docid_`。 -删除：~~全量 `std::vector windows_`~~。 -新增： -```cpp -// open 时拷贝的 window_region 原始字节（reader 必须自持，原因见下）。 -std::vector window_region_; // owned copy -// 每个 super-block 在 window_region_ 内的 [off,len) 与其绝对 last_docid。 -struct SbSpan { uint64_t off; uint64_t len; uint64_t last_docid; }; -std::vector sb_spans_; // size n_super_，resident -// 惰性解码缓存：每 super-block 一段已解码 WindowMeta。mutable 以支持 const 访问。 -mutable std::vector> sb_cache_; // size n_super_，初始全空 -mutable std::vector sb_decoded_; // size n_super_，0=未解码/1=已解码 -mutable uint32_t decoded_sb_count_ = 0; // 测试 seam：已解码的 distinct 块数 -uint32_t n_windows_ = 0; // = h.n，open 时记录（不再由 windows_.size() 推导） -``` - -**为什么必须自持 window_region 拷贝（关键正确性约束）**：现行 reader 注释"does not retain the input"。`windowed_posting.cpp:114-118` 在局部 `BatchRangeFetcher fetcher` 上 fetch 后 `return FrqPreludeReader::open(fetcher.get(h), prelude)`，open 返回后 fetcher 析构，prelude Slice 指向已释放缓冲。要惰性解码就必须保留 window-row 字节，因此在 open 时把 `window_region` 这段（仅 ~20-30KB 量级，且 ≤ prelude 总长）一次性 memcpy 进 `window_region_`。该 memcpy 远比"解析全部行"廉价，故净收益为正。拷贝用 `doris::snii::resize_uninitialized`（T19，立即被 memcpy 全量覆写）；无 T19 时退化为 `resize`。 - -### 算法 - -**open(prelude)**： -1. `parse_header` + `verify_covered_crc`（不变，crc 仍只覆盖 header+super_block_dir）。 -2. `decode_super_block_dir` → `rows`（含每块 block_off/block_len/last_docid，已校验 contiguous、in-bounds、单调 last_docid）。 -3. 计算 `window_region` 边界（不变），把该段 memcpy 进 `window_region_`；据 `rows` 填 `sb_spans_`、`sb_last_docid_`、`n_super_`、`n_windows_=h.n`；`sb_cache_/sb_decoded_` 按 n_super_ 置空。 -4. **派生块长**：若 `n_super_>0`，`ensure_super_block_decoded(n_super_-1)`（解码最后一块），取其最后一个 window 的 `dd_off+dd_disk_len` 作为 `dd_block_len_`，`freq_off+freq_disk_len`（has_freq 时）作为 `freq_block_len_`；N==0 时二者为 0。利用 contiguous tiling 不变量：window i 的 `dd_off` = 前缀和，故末窗的 `dd_off+dd_disk_len` == 全块长。 - -**ensure_super_block_decoded(sb)（mutable，const 可调）**： -- 若 `sb_decoded_[sb]` 已置位则直接返回。 -- 取 `prev_last = (sb==0) ? 0 : sb_last_docid_[sb-1]`（**跨块 win_base 链可由 resident 的 sb_last_docid_ 独立重建**，无需顺序解码）。 -- `first_window = (sb==0)`（仅全局窗 0 的 doc_count 校验用 first_window=true；`decode_one_block` 内以 `windows->empty()` 判定 first，这里改为传入显式 first 标志或预置 prev_last 使语义等价 —— 实现上把"是否首窗"逐行计算为 `sb==0 && i==0`）。 -- 用 `decode_one_block` 等价逻辑解码 `window_region_` 内 `[sb_spans_[sb].off, len)` 的 `rows=min(group_size_, n_windows_ - sb*group_size_)` 行进 `sb_cache_[sb]`；末尾校验 `prev_last == sb_spans_[sb].last_docid`（保留 sb 边界 last_docid 一致性校验）、块内无 trailing 字节、**块内 dd/freq contiguity**（首窗 dd_off 起点 = 该块在全局的起始 dd_off，块内逐窗 dd_off=running）。 -- 置 `sb_decoded_[sb]=1`，`++decoded_sb_count_`。 - -**window(w)**：算 `sb=w/group_size_`，`ensure_super_block_decoded(sb)`，返回 `sb_cache_[sb][w - sb*group_size_]`。越界返回 `InvalidArgument`（不变）。 - -**locate_window(docid)**：Level-1 在 resident `sb_last_docid_` 上二分（无需解码）；定位到 sb 后 `ensure_super_block_decoded(sb)`，Level-2 在该块内线性/二分。`docid > 全局末窗 last_docid` 的 found=false 快路用 `sb_last_docid_.back()` 即可，**无需解码任何块**。 - -### FORMAT-COMPATIBILITY 结论 -**reader/writer-only，零在盘变更**。build 路径一字未改，`build_frq_prelude` 输出字节级不变；在盘 prelude 布局、crc 覆盖范围、win_mode 语义全部不变。 - -### CONCURRENCY 结论 -**N/A，无共享可变状态**。已读码确认 `FrqPreludeReader` 全部实例均为 **request-scoped（每查询）**：内嵌于 `TermPlan`（`docid_conjunction.h:33`，per-query plan 结构）、scoring 的 `LazyTermCursor`、以及 `windowed_posting`/`docid_posting_reader` 的栈局部；**从不**存放于被 `InvertedIndexSearcherCache` 跨线程共享的 `LogicalIndexReader`（grep 确认 logical_index_reader 未持有 FrqPreludeReader/TermPlan）。因此新增 `mutable` 惰性缓存为单线程（单查询）访问，**无需锁、无原子**；解码为纯 CPU、读自 owned 缓冲，临界区内无任何 FileReader IO / zstd / crc-over-IO，天然满足 NO-IO-UNDER-LOCK（因为根本没有锁）。**约束（必须在头注释固化为不变量）**：FrqPreludeReader 必须保持 per-query 生命周期，严禁置于跨线程共享的 reader 上；若未来需共享，须改为 request-scoped 副本或加分片锁（解压在锁外）。 - -## 4. 依赖 -- 硬依赖：无。 -- 软依赖 / shared infra：`doris::snii::resize_uninitialized`（T19）用于 window_region 拷贝；缺失时 `std::vector::resize` 替代，功能不受影响。 -- 不依赖、不修改其他任务；不与 T04（per-reader dict-block 缓存）共享状态（本任务缓存在 per-query 的 FrqPreludeReader 内，非共享 reader，H1/H2 风险不适用）。 -

-### 是否最优（否，作为核心直接依赖时次优） -1. **read_batch 缺失（关键）**：薄接口的 `read_batch` 承载「批 = 并发 = 约一次 round-trip」的 range 合并契约（`file_reader.h:30-33`），`S3FileReader::read_batch` 真实做 16 路 `std::async` 扇出（`s3_object_store.h:80`），`BatchRangeFetcher` 也依赖此契约。Doris `io::FileReader` 只有单点 `read_at`，无批量/合并语义。 -2. **缓冲 API 不匹配**：SNII 用 `std::vector*` 自管理 resize（`file_reader.h:28`），Doris 要求调用方预分配 `Slice` + `size_t* bytes_read`（`file_reader.h:80-81`）。直依需在所有 use-site 改写缓冲生命周期。 -3. **依赖重**：Doris `io::FileReader` 继承 `doris::ProfileCollector`（`file_reader.h:68`）；`io::FileWriter` 携带 block_file_cache / `FileCacheAllocatorBuilder` / S3 committer（`file_writer.h:24-26,99-129`）。这与 CLucene-free、可独立构建的 snii 核心目标冲突。 -4. **IOContext 线程化耦合**：生产读路径需 `thread_local` `ScopedIOContext` + section 分类（`snii_doris_adapter.cpp:157-175,264-269`），属 Doris 特有，不应渗入核心接口。 -5. **多后端**：薄接口已有核心后端 `LocalFileReader`/`MeteredFileReader`/`S3ObjectStore`（`grep` 确认 3 个）+ 写侧 `LocalFileWriter`/`S3FileWriter`。直依 Doris 会破坏这些独立/测试后端（`MeteredFileReader` 是 serial-round / range-GET 的测试标尺，`metered_file_reader.h:23`）。 -

Problem Summary: Seven independent writer/build-path hotspots in the SNII inverted-index container did redundant CPU work or per-term heap churn on the SPIMI build path. Each is reader/writer-only with zero on-disk byte change, guarded by a deterministic op-count plus value/byte-equivalence unit gate (build wall-time is dominated by zstd/IO, so it stays report-only per the task specs). - T11 PFOR choose_width: replace the O(maxw*n) triple bits_for scan with a single O(n) histogram + suffix-sum; pfor_encode reuses the cached per-value widths (no third pass, no per-run low/exc heap vectors). value_width(0)==0 guards the clz UB. Output bytes are identical (cost formula and ascending-w strict-'<' tie-break preserved). - T12 fused freq stats: compute each term's total + max freq in one pass, reused by validate_term's has_prx position-count check, sum_total_term_freq, ttf_delta and max_freq (was 3-4 separate scans). Values bit-identical. - T13 compact_posting_pool: move the per-byte append_byte / Cursor::has_next / next into the header as inline so the SPIMI ingest/drain TU can inline them (no cross-TU call per byte). Pure code move; cold helpers stay out-of-line. - T14 prx auto-mode: derive the per-doc deltas once; sub-512B windows (the Zipfian majority) skip materializing the throwaway raw-plaintext ByteSink, gated by an exact varint byte-count so the codec choice at the threshold is byte-identical. - T15 spill K-way merge: order runs by the precomputed integer string_rank instead of random vocab string compares; merged postings byte-identical (rank is a lexicographic bijection on the dense vocab). - T16 DictBlockBuilder: move each DictEntry into entries_ (estimate-before-move) and drop the dead prev_term_ member; finish() unchanged so the on-disk block is byte-identical. - T17 MemoryReporter: skip the per-token zero-delta locked fetch_add (arena grows about every 32 KiB); over_cap() stays unconditional so the unified gate-2 spill contract holds. Reader/writer-only, no format change, no reimport. ### Release note None ### Check List (For Author) - Test: Unit Test (SniiPforTest/SniiPforPerfTest, SniiWriterTest, SniiCompactPostingPoolTest, SniiPrxPodTest/SniiPrxPodCounterTest, SniiSpillMergeTest, SniiDictBlockTest, SniiSpimiTermBufferTest; all 602 *Snii* tests pass) - Behavior changed: No (output bytes/values identical; deterministic op-count gates only) --- be/src/storage/index/snii/encoding/pfor.cpp | 136 ++++-- be/src/storage/index/snii/encoding/pfor.h | 14 + .../storage/index/snii/format/dict_block.cpp | 14 +- be/src/storage/index/snii/format/dict_block.h | 15 +- be/src/storage/index/snii/format/prx_pod.cpp | 170 +++++-- be/src/storage/index/snii/format/prx_pod.h | 17 + .../snii/writer/compact_posting_pool.cpp | 52 --- .../index/snii/writer/compact_posting_pool.h | 74 +++ .../snii/writer/logical_index_writer.cpp | 81 +++- .../index/snii/writer/logical_index_writer.h | 39 +- .../index/snii/writer/spill_run_codec.cpp | 53 ++- .../index/snii/writer/spill_run_codec.h | 29 +- .../index/snii/writer/spimi_term_buffer.cpp | 22 +- .../storage/index/snii/encoding/pfor_test.cpp | 386 ++++++++++++++++ .../index/snii/format/dict_block_test.cpp | 226 ++++++++++ .../index/snii/format/prx_pod_test.cpp | 355 +++++++++++++++ .../snii/writer/compact_posting_pool_test.cpp | 253 +++++++++++ .../logical_index_writer_freq_stats_test.cpp | 423 ++++++++++++++++++ .../snii/writer/spill_run_codec_test.cpp | 408 ++++++++++++++++- .../snii/writer/spimi_term_buffer_test.cpp | 190 ++++++++ 20 files changed, 2757 insertions(+), 200 deletions(-) create mode 100644 be/test/storage/index/snii/writer/logical_index_writer_freq_stats_test.cpp diff --git a/be/src/storage/index/snii/encoding/pfor.cpp b/be/src/storage/index/snii/encoding/pfor.cpp index c672729007ffda..08732fc7728acf 100644 --- a/be/src/storage/index/snii/encoding/pfor.cpp +++ b/be/src/storage/index/snii/encoding/pfor.cpp @@ -18,6 +18,7 @@ #include "storage/index/snii/encoding/pfor.h" #include +#include #include #include #include @@ -39,32 +40,57 @@ inline uint64_t load_u64_le(const uint8_t* p) { return v; } -uint8_t bits_for(uint32_t v) { - uint8_t b = 0; - while (v) { - ++b; - v >>= 1; - } - return b; +// TEST-ONLY seam backing doris::snii::testing::pfor_width_evals(). value_width() +// is the SINGLE per-value bit-width evaluation point on the encode path, so this +// counter equals the number of values processed per run -- the deterministic +// signal that the histogram path scans each value exactly once (vs the former +// O(maxw*n) re-scan).

Problem Summary: Four reader/encode-path micro-optimizations on the SNII inverted index, all reader/writer-only with zero on-disk byte change, each guarded by a deterministic op-count or byte/value-equivalence unit gate. - T21 CRC32C: production crc32c already delegates to the bundled hardware-accelerated Google crc32c library, so this adds BE_TEST-only reference paths (slice-by-8, serial SSE4.2, and a 3-way interleaved SSE4.2 + GF(2) shift-combine) that prove, byte for byte across sizes/alignments, that the production path equals canonical CRC32C and the hardware path is engaged. Compiled out of release; on-disk CRCs unchanged. - T22 single-copy framing: write_pfor/write_raw/write_zstd_compressed/SectionFramer and emit_region's raw branch now write header+payload directly into the target sink and CRC the sink sub-slice, dropping a per-window temporary ByteSink + copy; ByteSink::reserve() removes bitpack's realloc churn. On-disk bytes byte-identical. - T24 phrase-prefix: anchor the tail-position enumeration on the sparsest exact term (min per-doc span) with an underflow guard, and hoist the expected-docid vector out of the per-tail loop (built once). Deterministic seams anchor_iterations / expected_docids_build. Results identical (the sole consumer uses binary_search). - T25 build/meta: (A) skip the redundant per-row phrase-bigram sort when analyzer positions are already monotonic (is_sorted guard) and drop the dead secondary key; (B) charge sti_/dbd_/anchor heap bytes in memory_usage() so the searcher cache is not under-billed; (C) reuse the query-level analyzer in the phrase branch instead of rebuilding it per segment. T20 (FrqPrelude window-ref accessor) and T23 (FrqPrelude lazy super-block decode) were prototyped and then dropped: a concurrent warm-CPU benchmark using per-query profile CPU (InvertedIndexFilterTime / ScannerCpuTime, median of repeats, normalized against an unchanged CLucene-V3 control) showed no measurable benefit -- for full-scan queries the lazy-decode machinery's overhead cancels the zero-copy savings, and the intended selective-query gain is microseconds against seconds-scale queries, far below the measurement noise floor. The added complexity (owned window-region copy, per-window ensure-decode check, two-level super-block cache) was not justified. Reader/writer-only, no format change, no reimport. New deterministic + functional unit tests; all *Snii* suites (649 tests) pass. ### Release note None ### Check List (For Author) - Test: Unit Test (SniiCrc32cTest/SniiCrc32cPerfTest, SniiPrxPod*/SniiFrqPodTest, SniiPhraseQueryTest, SniiPhraseBigramBuildTest, SniiSegmentReaderTest; 649 *Snii* tests pass) - Behavior changed: No (query results and on-disk bytes identical; op-count + byte-golden gates) --- .../storage/index/snii/encoding/byte_sink.h | 10 + be/src/storage/index/snii/encoding/crc32c.cpp | 278 ++++++++++++ be/src/storage/index/snii/encoding/crc32c.h | 29 ++ be/src/storage/index/snii/encoding/pfor.cpp | 7 + .../index/snii/encoding/section_framer.cpp | 18 +- .../storage/index/snii/format/dict_block.cpp | 10 + be/src/storage/index/snii/format/dict_block.h | 8 + .../index/snii/format/dict_block_directory.h | 6 + be/src/storage/index/snii/format/frq_pod.cpp | 23 +- be/src/storage/index/snii/format/prx_pod.cpp | 50 +- .../index/snii/format/sampled_term_index.cpp | 8 + .../index/snii/format/sampled_term_index.h | 18 + .../snii/query/internal/query_test_counters.h | 82 ++++ .../storage/index/snii/query/phrase_query.cpp | 63 ++- .../snii/reader/logical_index_reader.cpp | 11 +- .../storage/index/snii/snii_index_reader.cpp | 20 +- .../storage/index/snii/snii_index_writer.cpp | 66 +-- be/src/storage/index/snii/snii_index_writer.h | 6 + .../index/snii/snii_phrase_bigram_build.h | 101 +++++ .../index/snii/encoding/crc32c_test.cpp | 236 ++++++++++ .../index/snii/format/frq_pod_test.cpp | 158 +++++++ .../index/snii/format/prx_pod_test.cpp | 293 ++++++++++++ be/test/storage/index/snii_query_test.cpp | 326 ++++++++++++++ be/test/storage/index/snii_writer_test.cpp | 426 ++++++++++++++++++ 24 files changed, 2159 insertions(+), 94 deletions(-) create mode 100644 be/src/storage/index/snii/encoding/crc32c.cpp create mode 100644 be/src/storage/index/snii/query/internal/query_test_counters.h create mode 100644 be/src/storage/index/snii/snii_phrase_bigram_build.h create mode 100644 be/test/storage/index/snii_writer_test.cpp diff --git a/be/src/storage/index/snii/encoding/byte_sink.h b/be/src/storage/index/snii/encoding/byte_sink.h index e9072bf60b547a..e96ae112e20a31 100644 --- a/be/src/storage/index/snii/encoding/byte_sink.h +++ b/be/src/storage/index/snii/encoding/byte_sink.h @@ -41,6 +41,16 @@ class ByteSink { const std::vector& buffer() const { return buf_; } Slice view() const { return Slice(buf_); } + // Reserves capacity for `additional` MORE bytes on top of the current size(), + // so a caller about to append a known-length run pays at most one reallocation + // instead of the geometric-growth reallocs a byte-at-a-time put_u8 loop would + // trigger.

T18 drops them, folding the trimmed layout into the pre-launch v1 format (no dual path, no version bump). - Removed the three running-sum offsets dd_off / freq_off / prx_off from each window row: they are pure prefix sums the reader now derives via three uint64 accumulators threaded across super-blocks (same lifetime as prev_last), each guarded by checked_add_u64 -> Status::Corruption on overflow. validate_region_layout's off cross-checks become tautological and are dropped; the length-overflow and dd/freq block-len sum checks, plus all windowed_posting InBounds checks, are retained. - Conditionalized dd_uncomp_len / freq_uncomp_len: written and read only when the matching win_mode zstd bit is set. dd/freq are always raw-encoded in practice, so these two columns were 100% redundant; raw regions derive uncomp_len == disk_len. This is a byte-count and eager-parse varint-decode-count reduction (no round-trip change -- the prelude is already a single BatchRangeFetcher range). A docs+positions row shrinks ~30-40%; a df=500K term (~500 windows) saves ~6KB of prelude, an extreme stop-word (~5000 windows) ~60KB. Public WindowMeta / FrqPreludeReader signatures are unchanged (dd_off/freq_off/prx_off remain, now derived); the writer's in-memory data flow is unchanged. FORMAT: on-disk bytes change. Confirmed pre-launch (no `lifecycle: launched` index); folded into v1, no format-version bump, reader/writer symmetric. kSlimRows = 1U<<2 is reserved as a documented flag extension point (not emitted) for a post-launch dual path. ### Release note None ### Check List (For Author) - Test: Unit Test (SniiFrqPreludeTest FP-01..FP-09 + the existing SniiFrqPrelude suite; 658 *Snii* tests pass): round-trip derived-offset equality, exact byte-shrink (~33%), multi-super-block cross-block accumulation, zstd conditional field, truncation and sum-overflow -> Corruption, and an E2E windowed-term query proving identical docids and a single coalesced frq-region round-trip at the (shrunk) prelude. - Behavior changed: query results and index semantics identical; the on-disk .frq prelude bytes shrink (format change; pre-launch fold into v1, re-import required). --- .../storage/index/snii/format/frq_prelude.cpp | 100 +++- .../storage/index/snii/format/frq_prelude.h | 40 +- .../index/snii/format/frq_prelude_test.cpp | 42 +- .../storage/index/snii_frq_prelude_test.cpp | 520 ++++++++++++++++++ 4 files changed, 644 insertions(+), 58 deletions(-) create mode 100644 be/test/storage/index/snii_frq_prelude_test.cpp diff --git a/be/src/storage/index/snii/format/frq_prelude.cpp b/be/src/storage/index/snii/format/frq_prelude.cpp index 4e62b54f6e277e..cbd67ee6feefdc 100644 --- a/be/src/storage/index/snii/format/frq_prelude.cpp +++ b/be/src/storage/index/snii/format/frq_prelude.cpp @@ -110,23 +110,32 @@ Status validate_input(const FrqPreludeColumns& cols, ByteSink* out) { // Encodes one window row into a per-block sink. last_docid_delta is the row's // absolute last_docid minus prev_last (the previous window's absolute last). +// +// dd_off/freq_off/prx_off are NOT serialized: each was a pure running prefix sum +// of the per-window disk/prx lengths, which the reader reconstructs (see +// decode_window_row / RunningOffsets). dd_uncomp_len/freq_uncomp_len are written +// ONLY when the region's zstd win_mode bit is set; a raw region's uncomp_len is +// defined to equal its disk_len (open_region enforces uncomp_len == disk_len on +// raw region bytes), so the reader derives it without a stored field. void encode_window_row(const WindowMeta& m, bool has_freq, bool has_prx, uint64_t prev_last, ByteSink* block) { + const uint8_t win_mode = make_win_mode(m, has_freq); block->put_varint64(static_cast(m.last_docid) - prev_last); block->put_varint64(m.doc_count); - block->put_u8(make_win_mode(m, has_freq)); - block->put_varint64(m.dd_off); + block->put_u8(win_mode); block->put_varint64(m.dd_disk_len); - block->put_varint64(m.dd_uncomp_len); + if ((win_mode & frq_win_mode::kDdZstd) != 0) { + block->put_varint64(m.dd_uncomp_len); + } block->put_fixed32(m.crc_dd); if (has_freq) { - block->put_varint64(m.freq_off); block->put_varint64(m.freq_disk_len); - block->put_varint64(m.freq_uncomp_len); + if ((win_mode & frq_win_mode::kFreqZstd) != 0) { + block->put_varint64(m.freq_uncomp_len); + } block->put_fixed32(m.crc_freq); } if (has_prx) { - block->put_varint64(m.prx_off); block->put_varint64(m.prx_len); } block->put_varint64(m.max_freq); @@ -309,9 +318,22 @@ Status check_win_mode(uint8_t mode, bool has_freq) { return Status::OK(); } -// Decodes one window row, advancing prev_last to this window's absolute last. +// Running per-block byte offsets, chained across windows AND across super-blocks +// with the same lifetime as prev_last: dd/freq are prefix sums of the per-window +// on-disk region lengths, prx the prefix sum of prx lengths.

G01: (A) reader falls back to the generic positions phrase path when a bigram term is absent AND the segment meta declares pruning (legacy segments keep miss==empty); (B) writer skips materializing bigram terms with final df < max(64, doc_count/10000) (config snii_bigram_prune_min_df, 0=off) at the single process_term choke point -- survivor postings complete, pruned terms leave no dict/posting/bloom trace; surviving bigrams write docs+freq only (no positions; the bigram hit path never reads prx); threshold recorded as a CRC-framed, skippable per-index meta field (old readers skip, new readers default 0=legacy); (C) SpimiTermBuffer::add_bigram_token interns via piecewise FNV-1a hash + fragment equality, building the owned string only on first occurrence (kills ~2 allocations per token pair). Independent adversarial review: clean. 674/674 *Snii* tests pass (16 new: hot-direct/ cold-fallback equality vs unpruned control, docs-only layout, threshold determinism, legacy-miss, phrase_prefix regression, piecewise-hash equivalence). --- be/src/common/config.cpp | 3 + be/src/common/config.h | 8 + be/src/storage/index/index_file_writer.cpp | 28 ++ .../index/snii/format/format_constants.h | 8 + .../index/snii/format/per_index_meta.cpp | 25 ++ .../index/snii/format/per_index_meta.h | 15 ++ .../storage/index/snii/format/phrase_bigram.h | 64 ++++- .../snii/query/internal/query_test_counters.h | 13 +- .../storage/index/snii/query/phrase_query.cpp | 17 ++ .../index/snii/reader/logical_index_reader.h | 7 + .../storage/index/snii/snii_index_writer.cpp | 7 +- .../snii/writer/logical_index_writer.cpp | 94 ++++++- .../index/snii/writer/logical_index_writer.h | 46 +++- .../index/snii/writer/spimi_term_buffer.cpp | 38 +++ .../index/snii/writer/spimi_term_buffer.h | 88 ++++++- .../index/snii/format/per_index_meta_test.cpp | 30 +++ .../query/phrase_bigram_prune_query_test.cpp | 242 ++++++++++++++++++ .../snii/writer/bigram_prune_writer_test.cpp | 190 ++++++++++++++ .../snii/writer/spimi_bigram_token_test.cpp | 154 +++++++++++ be/test/storage/index/snii_query_test_util.h | 7 +- 20 files changed, 1048 insertions(+), 36 deletions(-) create mode 100644 be/test/storage/index/snii/query/phrase_bigram_prune_query_test.cpp create mode 100644 be/test/storage/index/snii/writer/bigram_prune_writer_test.cpp create mode 100644 be/test/storage/index/snii/writer/spimi_bigram_token_test.cpp diff --git a/be/src/common/config.cpp b/be/src/common/config.cpp index 9ec587bd100ec5..0d97a6ad2fc8ff 100644 --- a/be/src/common/config.cpp +++ b/be/src/common/config.cpp @@ -1298,6 +1298,9 @@ DEFINE_mDouble(inverted_index_ram_buffer_size, "512"); // -1 indicates not working. // Normally we should not change this, it's useful for testing.

G01's pruning changed per-segment hidden-dict density and exposed it (MATCH_PHRASE_PREFIX 'united stat' returned 1 instead of 74880 on a pruned 1M-doc segment); legacy segments carried the same latent bug. Fix: enumerate via visit_prefix_terms, skip hidden bigram terms inside the callback (no budget charge), count only real tails. Unconditional -- hidden entries never charge user-visible expansion budget on any segment layout. 676/676 *Snii* tests (2 new: mixed hot/pruned tail pairs equal unpruned control; expansion-budget nail that fails pre-fix). --- .../storage/index/snii/query/phrase_query.cpp | 27 ++- .../query/phrase_bigram_prune_query_test.cpp | 158 ++++++++++++++++++ 2 files changed, 181 insertions(+), 4 deletions(-) diff --git a/be/src/storage/index/snii/query/phrase_query.cpp b/be/src/storage/index/snii/query/phrase_query.cpp index ab4aef65ff9c1f..eaae6db67258fa 100644 --- a/be/src/storage/index/snii/query/phrase_query.cpp +++ b/be/src/storage/index/snii/query/phrase_query.cpp @@ -1359,11 +1359,30 @@ Status phrase_prefix_query(const LogicalIndexReader& idx, const std::vector
